january 1992 5 philips semiconductors preliminary speci?cation sound fader control circuit for car radios TEA6330T functional description this bipolar ic is an i 2 c-bus controlled sound/volume controller for car radios including fader function and the possibility of an external equalizer. the sound signal setting is performed by resistor chains in combination with multi-input operational amplifiers. the advantages of this principle are the combination of low noise, low distortion and a high dynamic range. the separated volume controls of the left and the right channel make the balance control possible. the value and the characteristic of the balance is controlled via the i 2 c-bus. the contour function is performed by setting an extra bass control and optional treble, depending on the actual volume position. its switching points and its range are also controllable via the i 2 c-bus. an interface is assigned behind the volume control to loop-in an equalizer (fig.2). in this case the treble control is switched off, and the bass control can be used to set the contour. low level control fader is included independent of the volume controls, because the TEA6330T has four driver outputs (for front and rear). an extra mute position for the front, the rear or for all channels is built in. the last function may be used for muting during preset selection. no external interface is required between the microcomputer and this circuit, for all switching and controlling functions are controllable via the two-wire i 2 c-bus. the separate mute-pin allows to switch the fader into mute position without using the i 2 c-bus. the on chip power-on reset sets the TEA6330T into the general mute mode. limiting values in accordance with the absolute maximum system (iec 134). ground pins 3 and 10 connected together. * equivalent to discharging a 200 pf capacitor through a 0 w series resistor. ** equivalent to discharging a 100 pf capacitor through a 1.5 k w series resistor. symbol parameter min. max. unit v p supply voltage (pin 18) 0 10 v p tot total power dissipation 0 700 mw t stg storage temperature range - 55 150 c t amb operating ambient temperature range - 40 85 c v esd electrostatic handling* for all pins - 300 v electrostatic handling** for all pins - 4000 v

january 1992 18 philips semiconductors preliminary speci?cation sound fader control circuit for car radios TEA6330T soldering 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 ic package databook (order code 9398 652 90011). re?ow 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. wave 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. repairing 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.
