FAN7033MP 15 applications information functional description the FAN7033MP is a stereo power amplifier capable of delivering 1.9w continuous rms(root mean square) power into 4 ? load with 1% thd(total harmonic distortion). at 10% thd, the FAN7033MP can deliver above 2w into 4 ? load. the FAN7033MP has 5 supply input pins. three among them are used for positive supply and the rest of them is for the ground. three positive supply input pins : pin3(pvdd2), pin10(pvdd1) and pin11(vdd) must be tied together. to improve the cross-talk between can nels, these pins are not connected internally. therefore, these pins must be externally connect ed on the pcb. pin 8 and the exposed pa d are allocated to ground. thus, the exposed pad must be connected to the ground. the FAN7033MP is provided with differential inputs. these inputs increase the common-mode noise immunity. furthermore, differential configuration in the input section helps to decrease total harmonic distortion and pop noise that occurs when shutdown is released. when only si ngle input is available, the distortion performance is slightly degraded. to save the standby power consumption, the FAN7033MP provides shutdown function. putting pin14(sd) to be low, the chip falls into shutdown mode. at this mode, it consumes micro power at the room temperature of 25c and this power consumption is only due to the leakage curre nt of the chip. this leakage current is the strong func- tion of the temperature. thus at the high ambient temperat ure, the shutdown current s lightly increases. the logic threshold of shutdown pin lies nearby vdd/2. so, the logi c threshold level does not follow ttl logic level. thus, when the users want to control the chip according to the ttl logic level, some kinds of logic-level-changing circuit may be needed. operation of the amplifier figure 1 shows the configuration of the single channel bt l(bridge-tied load) power amplifier. to make the differ- ential input configuration, the FAN7033MP uses several re sistor networks as depicted in figure 1. for the input resistor, 15k ? is used. this resistor converts the input voltage signal to the current signal. the converted current signal flows to the feedback resistor. for FAN7033MP, the feedback resistance is six time s larger than input resis- tance. thus, the gain is 12(about 21.6db). for the 5v supply, the input signal has 0.83vpeak voltage swing makes 10vpp output swing. the exact gain formula is given by as shown in equation (1), for the single-ended input case, the gain is also preserved. however, to get the same output swing with the differential input case, the input swing must be double comparing with the differential input swing. pcb layout and supply regulation metal trace resistance between the btl output and the pa rasitic resistance of the power supply line both heavily figure 1. configuration of power amplifier inn 90k ? 90k ? 90k ? 15k ? 15k ? 15k ? 15k ? 90k ? inp c inn c inp outp outn amp1 amp2 vdd/2 outp outn ? 12 inp inn ?

FAN7033MP 16 affect the output power. in order to obtain the maximum power depicted in the performance characteristics figures, outputs, power, and ground lines need wide metal trace. the parasitic resistance of the power line increases ripple noise and degrades the thd and psrr performance. to reduce such unwanted effect, a large capacitor must be connected between v dd pin and gnd pin as close as possible. to improve power supply regulation performance, use a capacitor with low esr. power supply bypassing selection of a proper power supply bypassing capacitor is critical to obtaining lower noise as well as higher power supply rejection. larger capa citors may help to increase immunity to the supply noise. however, considering eco- nomical design, attaching 10 f electrolytic capacitor or tantalum capacitor with 0.1 f ceramic capacitor as close as possible to the vdd pins are enough to get a good supply noise rejection. selection of input capacitor the input capacitors cinn and cinp block the dc voltage al so low frequency input sig nal. thus, these capacitors act as a high pass filter. when there are dc level differences between input source and the amplifier, these capac- itors block dc voltage and make easy connection. however, these capacitors limit the low frequency input signal. thus to cover the full audio frequency range, the values of these are very important. the input impedance and the capacitance of these capacitors stand for the low frequency characteristics and -3db frequency is where zin is the input equivalent impedance and c is the capacitance of the input capacitor. for FAN7033MP, the input has several resistors and these resistors determine the input impedance. in the normal condition, (-) input of the amplifier looks like a voltage source since the negative feedb ack topology makes (-) input virtually be the ac ground. thus, resistance between th e negative input of the amplifier and input pin is 15k ? . the resistance toward (+) inpu t is the summation of 15k ? and 90k ? . thus total input impedance is considering f l =20hz(the lowest frequency of the audio freqeuncy range), it is possible to get the capacitance value from equation(2) and (3) as follow: thus, cin must be higher than 0.606uf. in the application note, 1uf is chosen by considering input impedance vari- ation during the chip fabrication. when using a capacitor which has the po larity, customers must ca refully connect the capacitor. the input dc level of the FAN7033MP is a half of vdd. thus, if the dc level of a source is higher than vdd/2, the positive lead of the capacitor must be face d toward the source. shutdown mode in order to reduce power consumption while not in use, th e FAN7033MP contains a shutdown pin to externally turn- off bias circuitry. this shutdown feature turns the amplifier off when a logic low is placed on the shutdown pin. the trigger point between a logic low and logic high level is typi cally half-supply. it is best to switch between ground and supply to provide maximum device performance. by switching the shutdown pin to vdd , the FAN7033MP supply current draw will be minimized in idle mode. in either case, the shutdown pin should be tied to a definite voltages to avoid unwanted state changes. in many appplications, a microcontroller or microprocessor output is used to control the shutdown circuitry which provides a quick, smooth transition into shutdown. another so lution is to use a single-pole, single-throw switch in conjunction with an external pull-down resistor. when the switch is closed, the shutdown pin is connected to vdd and enables the amplifier. if the switch is open, then th e external pull-down resistor will disable the FAN7033MP. this scheme guarantees that the shutdown pin will no t float thus preventing unwanted state changes. f l 1 2 zin c ?? ---------------------------- - = (2) zin 15k ? 15k ? 90k ? + () || 13.125k ? == (3) cin 1 2 zin f l ?? ---------------------------- - 0.606uf = = (4)
FAN7033MP 17 single-ended input for the case, a source does not provide the fully differen tial signal, the residual input must be well treated. case(a) : for this case, input is left alone without any treatment, that is, input pin is floating. even the pin is float- ing, the btl amplifier works and drives load. however, th is configuration might cause unwanted noise at the output signal. furthemore, floated configuration decreases ps rr(power supply rejection ratio) and increase pop noise. case(b) : case(b) is strongly reco mmended. this configuration increases psrr and decreases pop noise as well. of cource, to get the best perform ance, cinp must be the same value with cinn. thd+n(total harmonic distortion plus noise) thd+n stands for linearity and output noise of the amplif ier as well. the FAN7033MP has the circuit for enhancing thd. in spite of that, to get low thd+ n, users should follow the recommendation: (1) use fully differential input configuration : a fully differential input makes low thd at output. thus, for a single- ended input case, thd+n slightly increaes. (2) do not miss c byp . c byp helps to increase psrr. thus, using this capacitor, it is possible to increase noise immunity from the supply line. (3) do not miss c sup . voltage fluctuation in supply line increases thd. thus, such voltage fluctuation must be reduced to get low thd by connecting this capacitor between all vdd pins and the ground as closely as possible. case (a) : residual input pin floating input 90k ? 90k ? 90k ? 15k ? 15k ? 15k ? 15k ? 90k ? floating c inn outp outn amp1 amp2 vdd/2 case (b) : ac coupling to ground input 90k ? 90k ? 90k ? 15k ? 15k ? 15k ? 15k ? 90k ? c inn c inp outp outn amp1 amp2 vdd/2
