1998 jul 02 6 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 7 functional description 7.1 addressing each pcf8591 device in an i 2 c-bus system is activated by sending a valid address to the device. the address consists of a fixed part and a programmable part. the programmable part must be set according to the address pins a0, a1 and a2. the address always has to be sent as the first byte after the start condition in the i 2 c-bus protocol. the last bit of the address byte is the read/write-bit which sets the direction of the following data transfer (see figs 3, 15 and 16). fig.3 address byte. 7.2 control byte the second byte sent to a pcf8591 device will be stored in its control register and is required to control the device function. the upper nibble of the control register is used for enabling the analog output, and for programming the analog inputs as single-ended or differential inputs. the lower nibble selects one of the analog input channels defined by the upper nibble (see fig.4). if the auto-increment flag is set the channel number is incremented automatically after each a/d conversion. if the auto-increment mode is desired in applications where the internal oscillator is used, the analog output enable flag in the control byte (bit 6) should be set. this allows the internal oscillator to run continuously, thereby preventing conversion errors resulting from oscillator start-up delay. the analog output enable flag may be reset at other times to reduce quiescent power consumption. the selection of a non-existing input channel results in the highest available channel number being allocated. therefore, if the auto-increment flag is set, the next selected channel will be always channel 0. the most significant bits of both nibbles are reserved for future functions and have to be set to 0. after a power-on reset condition all bits of the control register are reset to 0. the d/a converter and the oscillator are disabled for power saving. the analog output is switched to a high-impedance state.

1998 jul 02 8 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 7.3 d/a conversion the third byte sent to a pcf8591 device is stored in the dac data register and is converted to the corresponding analog voltage using the on-chip d/a converter. this d/a converter consists of a resistor divider chain connected to the external reference voltage with 256 taps and selection switches. the tap-decoder switches one of these taps to the dac output line (see fig.5). the analog output voltage is buffered by an auto-zeroed unity gain amplifier. this buffer amplifier may be switched on or off by setting the analog output enable flag of the control register. in the active state the output voltage is held until a further data byte is sent. the on-chip d/a converter is also used for successive approximation a/d conversion. in order to release the dac for an a/d conversion cycle the unity gain amplifier is equipped with a track and hold circuit. this circuit holds the output voltage while executing the a/d conversion. the output voltage supplied to the analog output aout is given by the formula shown in fig.6. the waveforms of a d/a conversion sequence are shown in fig.7. fig.5 dac resistor divider chain.

1998 jul 02 10 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 7.4 a/d conversion the a/d converter makes use of the successive approximation conversion technique. the on-chip d/a converter and a high-gain comparator are used temporarily during an a/d conversion cycle. an a/d conversion cycle is always started after sending a valid read mode address to a pcf8591 device. the a/d conversion cycle is triggered at the trailing edge of the acknowledge clock pulse and is executed while transmitting the result of the previous conversion (see fig.8). once a conversion cycle is triggered an input voltage sample of the selected channel is stored on the chip and is converted to the corresponding 8-bit binary code. samples picked up from differential inputs are converted to an 8-bit twos complement code (see figs 9 and 10). the conversion result is stored in the adc data register and awaits transmission. if the auto-increment flag is set the next channel is selected. the first byte transmitted in a read cycle contains the conversion result code of the previous read cycle. after a power-on reset condition the first byte read is a hexadecimal 80. the protocol of an i 2 c-bus read cycle is shown in chapter 8, figs 15 and 16. the maximum a/d conversion rate is given by the actual speed of the i 2 c-bus. fig.8 a/d conversion sequence.

1998 jul 02 12 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 7.5 reference voltage for the d/a and a/d conversion either a stable external voltage reference or the supply voltage has to be applied to the resistor divider chain (pins v ref and agnd). the agnd pin has to be connected to the system analog ground and may have a dc off-set with reference to v ss . a low frequency may be applied to the v ref and agnd pins. this allows the use of the d/a converter as a one-quadrant multiplier; see chapter 15 and fig.6. the a/d converter may also be used as a one or two quadrant analog divider. the analog input voltage is divided by the reference voltage. the result is converted to a binary code. in this application the user has to keep the reference voltage stable during the conversion cycle. 7.6 oscillator an on-chip oscillator generates the clock signal required for the a/d conversion cycle and for refreshing the auto-zeroed buffer amplifier. when using this oscillator the ext pin has to be connected to v ss . at the osc pin the oscillator frequency is available. if the ext pin is connected to v dd the oscillator output osc is switched to a high-impedance state allowing the user to feed an external clock signal to osc.
1998 jul 02 13 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 8 characteristics of the i 2 c-bus the i 2 c-bus is for bidirectional, two-line communication between different ics or modules. the two lines are a serial data line (sda) and a serial clock line (scl). both lines must be connected to a positive supply via a pull-up resistor. data transfer may be initiated only when the bus is not busy. 8.1 bit transfer one data bit is transferred during each clock pulse. the data on the sda line must remain stable during the high period of the clock pulse as changes in the data line at this time will be interpreted as a control signal. 8.2 start and stop conditions both data and clock lines remain high when the bus is not busy. a high-to-low transition of the data line, while the clock is high, is defined as the start condition (s). a low-to-high transition of the data line while the clock is high, is defined as the stop condition (p). fig.11 bit transfer. handbook, full pagewidth mbc621 data line stable; data valid change of data allowed sda scl fig.12 definition of start and stop condition. handbook, full pagewidth mbc622 sda scl p stop condition sda scl s start condition
1998 jul 02 14 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 8.3 system con?guration a device generating a message is a transmitter, a device receiving a message is the receiver. the device that controls the message is the master and the devices which are controlled by the master are the slaves. 8.4 acknowledge the number of data bytes transferred between the start and stop conditions from transmitter to receiver is not limited. each data byte of eight bits is followed by one acknowledge bit. the acknowledge bit is a high level put on the bus by the transmitter whereas the master also generates an extra acknowledge related clock pulse. a slave receiver which is addressed must generate an acknowledge after the reception of each byte. also a master must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. the device that acknowledges has to pull down the sda line during the acknowledge clock pulse, so that the sda line is stable low during the high period of the acknowledge related clock pulse. a master receiver must signal an end of data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. in this event the transmitter must leave the data line high to enable the master to generate a stop condition. fig.13 system configuration. mba605 master transmitter / receiver slave receiver slave transmitter / receiver master transmitter master transmitter / receiver sda scl fig.14 acknowledgement on the i 2 c-bus. handbook, full pagewidth mbc602 s start condition 9 8 2 1 clock pulse for acknowledgement not acknowledge acknowledge data output by transmitter data output by receiver scl from master

1998 jul 02 24 philips semiconductors product speci?cation 8-bit a/d and d/a converter pcf8591 17 soldering 17.1 introduction there is no soldering method that is ideal for all ic packages. wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. however, wave soldering is not always suitable for surface mounted ics, or for printed-circuits with high population densities. in these situations reflow soldering is often used. this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (order code 9398 652 90011). 17.2 dip 17.2.1 s oldering by dipping or by wave the maximum permissible temperature of the solder is 260 c; solder at this temperature must not be in contact with the joint for more than 5 seconds. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg max ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. 17.2.2 r epairing soldered joints apply a low voltage soldering iron (less than 24 v) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 c it may remain in contact for up to 10 seconds. if the bit temperature is between 300 and 400 c, contact may be up to 5 seconds. 17.3 so 17.3.1 r eflow soldering reflow soldering techniques are suitable for all so packages. reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several techniques exist for reflowing; for example, thermal conduction by heated belt. dwell times vary between 50 and 300 seconds depending on heating method. typical reflow temperatures range from 215 to 250 c. preheating is necessary to dry the paste and evaporate the binding agent. preheating duration: 45 minutes at 45 c. 17.3.2 w ave soldering wave soldering techniques can be used for all so packages if the following conditions are observed: a double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. the longitudinal axis of the package footprint must be parallel to the solder flow. the package footprint must incorporate solder thieves at the downstream end. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. maximum permissible solder temperature is 260 c, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 c within 6 seconds. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 17.3.3 r epairing soldered joints fix the component by first soldering two diagonally- opposite end leads. use only a low voltage soldering iron (less than 24 v) applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
