PIN CONFIGURATIONS

PIN

NAME

DESCRIPTION

1

Input(+)

Analog Ground for the amplifiers. A 1

µF 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.

2

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.

3

Output 1

Amplifier 1’ s output. The DC level is about (Vcc~0.7V)/2.

4

Vcc

DC supply voltage is applied to this pin( Vcc=2~16V).

5

GND

Ground pin.

6

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.

7

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” .

8

Ripple

Rejection

A capacitor at this pin increase power supply rejection, and affects turn-on time. This pin can be

left open if the capacitor at pin 1 is sufficient.
