• The voltage, Vref is the reference voltage given by the external bias voltage of pin 46.
• The input signal (Vin) through pin 2, 5, 10 and 47 are by the AP1 amplified one times (Rref1=Rfeed1) 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.
