• The voltage, Vref is the reference voltage given by the external bias voltage of the pin 45.
• The input signal (Vin) through pins 3, 6, 9 and 48 is amplified one times (Rref1 = Rfeed1) by the AP1 and then fed to the
• The level shift produces the current due to the difference between the input signal and the arbitrary reference signal. The
• If you desire to change the gain, the input buffer amplifier (BF) can be used.
• The output stage is the balanced transformerless (BTL) driver.
• The bias voltage Vr is expressed as below;
