Pin

Description

CD

1

Chip Disable-Digital input. A Logic “0” (<0.8V) sets normal operation. A Logic “1” ( 2V) sets the

power down mode. Input impedance is nominally 90k .

FC2

2

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

open if the capacitor at FC1 is sufficient.

FC1

3

Analog ground for the amplifiers. A 1.0uF capacitor at

this pin (with a 5.0uF capacitor at Pin 2)

provides (typically) 52dB 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 alternate input.

Vin

4

Amplifier input. This input capacitor a

nd resistor set low frequency rolloff and input impedance. The

DC supply voltage (+2V to +16V) is applied to this pin.

GND
