2. Keep the supply lines for the amplifier circuits separate from those for the motor drive circuit. This will reduce the
effect of motor noise on the amplifiers and help prevent voltage drop due to motor load from affecting the amplifier
supply voltage.
The recommended supply layout for the LA4165M power supply lines is shown below.
3. Do not connect a resistor to pin 6. The capacitor on this pin is being charged by a small current to determine the voice
sensor attack time. Bypassing this capacitor with a resistor will increase attack time, and possibly prevent the voice
sensor circuit from turning on.
4. The voice sensor circuit has approximately 6 dB hysteresis. It turns on at a voltage on pin 6 of approximately 1.1 V
and turns off at approximately 0.65 V. Biasing pin 6 higher than 0.65 V will cause it to remain on. The voice sensor
equivalent circuit is shown below.
