Description

1

-IN

Inverting Input of the Amplifier. The Voltage range can go from (VS– – 0.1V) to

(VS+ + 0.1V).

2

+IN

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

3

+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

4

-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 2.3V 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.
