The input signal (VIN) through pin #12,20 is amplified by 10k/10k times and then fed to the level shift. The level shift produces the current due to the difference between the input signal and the arbitary reference signal. The current produced as + ∆I and -∆I is fed into the driver Amp. The driver Amp. operates the power TR. of the output stage as the 2 times gain(1+10k/10k) according to the state of the input signal. ∆VV IN = V REF + ∆V∆I = ---------10K 10K DO + = V P + ∆I • 10K • 1 + ----------- = V P + 2∆V 10K 10K DO – = V P – ∆I • 10K • 1 + ----------- = V P – 2∆V 10K V OUT = ( DO+ ) – ( DO- ) = 4∆V V OUT GAIN = 20 log -------------- = 12dB ∆V If it is desired to change the gain, then the pin #3 or 25 can be used. The output stage is the balanced transformerless (BTL) driver. The bias voltage VP is expressed as 62K V P = ( VCC – V BE – V CE ( SAT ) ) × ---------------------------- + V CE ( SAT ) 60K + 62K VCC – V BE – V CE ( SAT ) = ------------------------------------------------------------ + V CE ( SAT ) 1.97 8 FAN8039D3 2. Thermal Shutdown VCC When the chip temperature reaches to 175°C, then the TSD circuit is activated. IREF This shuts down the bias current of the output drivers, and all the output drivers are in cut-off state. Thus the chip temperature begins to decrease. Output driver bias R1 Q0 R2 when the chip temperature falls to 150°C, the TSD circuit is deactivated and the output drivers are normally operated. Hysteresis Ihys R3 The TSD circuit has the hysteresis temperature of 25°C. 3. Power Save Function When the pin22 is high, the TR Q3 is turned on and Q4 is off, so the bias circuit is enabled. On the other hand, when the pin22 is Low (GND) , the TR Q3 is turned off and Q4 is on, so the bias circuit is disabled. That is, this function will cause all the circuit blocks of the chip except for the variable regulator to be in the off state. thus the low power quiescent state is established VCC Main Bias (except for variable reg.) Q4 22 Q3 Truth table is as follows; Pin#22 FAN8039D3 High Power Save Off Low Power Save On 4. Variable Regulator The VREF is the output voltage of the referenced biasing circuit and is the reference voltage of the regulator. (VREF=2.5V) The external circuit is composed of a capacitor, 33uF, which is used as a ripple eliminator The output voltage, VOUT is decided as follows.
