Application Information

1. Standby/Mute Input
FAN8006D3 have 2 independent standby inputs that is , pin #7(STBY2) and pin #20(STBY1), and 1 independent mute input(pin #7) . Th e digital logics of the se functions are as below.
STBY1=>Low STBY1=>High STBY2
Mute=>Low Mute=>High Mute=>Low Mute=>High High Low

CH2 - - - - operate standby
2. Mute Timing Chart
If the mute input( pin #6) voltage rises above 2.0V, the output(CH1) current can be muted under normal operating conditions, make sure to open pin #7 or pull it down below 0.5V. Below figure is high impedanc e mu te timing chart.

• The reference voltage BIAS is given externally through pin 1.
• The input signal is ampl ified by (20K/10K) times and the n fed to the current conveyor type 2 ci rcuit and the power amp circuit.
• The power amp circuit produces the diffe r ential output vol tages and drives two output power amplifier circu its.
• Since the differential gain of the power amplifier is equal to 2 × (1+10K / 10K) , the output signal of the input OP-amp is amplified totally 8.
• If the total gain is insufficient or large, external resistor can be used to adjust the gain.
