Definition

1

CD

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

≥2.0 V) sets the power down

mode. Input impedance is nominally 90 kΩ.

2

FC2

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.

3

FC1

Analog ground for the amplifiers. A 1.0

µF capacitor at this pin (with a 5.0 µF capacitor at Pin 2) provides

(typically) 52 dB 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.

4

VIN

Amplifier input. The input capacitor and resistor set low frequency rolloff and input impedance. The feedback

resistor is connected to this pin and VO1.

5

V01

Amplifier Output #1. The dc level is

6

VCC

DC supply voltage (+2.0 V to +16 V) is applied to this pin.

7

GND

Ground pin for the entire circuit.

8

V02

Amplifier Output #2. This signal is equal in amplitude, but 180

° out--of--phase with that at VO1. The dc level is
