BLOCK DIAGRA

REF (Pin 1): Reference Input. Sets the output level when

the difference between the inputs is zero.

–IN (Pin 2): Inverting Input. Connects a 1MΩ resistor to

the op amp’s inverting input. Designed to permit high

voltage operation.

+IN (Pin 3): Noninverting Input. Connects a 1MΩ resistor

to the op amp’s noninverting input. Designed to permit

high voltage operation.

V– (Pin 4): Negative Power Supply. Can be either ground

(in single supply applications) or a negative voltage (in

split supply applications).

GAIN2 (Pin 5): Gain = 10 Select Input. Configures the

amplifier for a gain of 10 when connected to the GAIN1 pin.

The gain is equal to one when both GAIN2 and GAIN1 are

open. See Applications section for additional functions.

OUT (Pin 6): Output. VOUT = G • (V+IN – V–IN) + VREF, in the

basic configuration.

V+ (Pin 7): Positive Power Supply. Can range from 2.7V to

36V above the V– voltage.

GAIN1 (Pin 8): Gain = 10 Select Input. Configures the

amplifier for a gain of 10 when connected to the GAIN2 pin.

The gain is equal to one when both GAIN1 and GAIN2 are

open. See Applications section for additional functions.
