Description

-IN

Negative (inverting) input

+IN

Positive (noninverting) input.

-INA, -INB

-INC, -IND

Inverting Input of the Amplifier. The voltage range can go from (VS– – 0.2V) to (VS+ +

0.2V).

+INA, +INB

+INC, +IND

Non-Inverting Input of Amplifier. This pin has the same voltage range as -IN.

+VS

Positive Power Supply. The voltage is from 2.3V to 5.5V. Split supplies are possible as

long as the voltage between VS+ and VS– is between 2.3V and 5.5V. A bypass capacitor

of 0.1μF as close to the part as possible should be used between power supply pins or

between supply pins and ground.

-VS

Negative Power Supply. It is normally tied to ground. It can also be tied to a voltage

other than ground as long as the voltage between VS+ and VS– is from 2.7V to 5.5V. If it

is not connected to ground, bypass it with a capacitor of 0.1μF as close to the part as

possible.

OUTA, OUTB

OUTC, OUTD

The output of the Amplifier.

OUT

Output.

NC

No Connection.
