PIN CONFIGURATIONS
PIN NAME
DESCRIPTION
1
Mute This pin can be used to power down the IC to converse power, or for muting, or both. When at a
logic “LOW” (less than 0.8V), the IC is enabled for normal operation. When at a logic “HIGH” (2V
to Vcc), the IC is disabled. If Mute is open, that is equivalent to a logic “LOW”.
2 Ripple A capacitor at this pin increase power supply rejection, and affects turn-on time. This pin can be
Rejection left open if the capacitor at pin 1 is sufficient.
3 Input(+) Analog Ground for the amplifiers. A 1µF capacitor at this pin ( with a 5µF capacitor at pin 8)
provides 52dB( typ) of power supply rejection. Turn-on time of the circuit is affected by the
capacitor on this pin. This pin can be used as an alternative input.
4 Input(-) Amplifier input. The input capacitor and resistor set low frequency roll-off and input impedance.
The feedback resistor is connected between this pin and output 1.
5 Output 1 Amplifier 1’s output. The DC level is about (Vcc~0.7V)/2.
6
Vcc DC supply voltage is applied to this pin(Vcc=2~16V).
7
GND Ground pin.
8 Output 2 Amplifier 2’s output. This signal is equal in amplitude, but 180°out of phase with that output 1,
the DC level is about (Vcc~0.7V)/2.
