PIN CONFIGURATIONS

NAME

DESCRIPTION

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.

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.

Output 1

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

VCC

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

GND

Ground pin.

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.

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”.

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.
