DESCRIPTION

The INA2132 is a dual low power, unity-gain difference

amplifier offering excellent value at very low

cost. Each channel consists of a precision op amp with

a laser-trimmed precision resistor network, providing

accurate gain and high common-mode rejection. Excellent

TCR tracking of the resistors maintains gain

accuracy and common-mode rejection over temperature.

The internal op amp’s common-mode range

extends to the negative supply—ideal for single-supply

applications.

The difference amplifier is the foundation of many

commonly used circuits. The INA2132 provides this

circuit function without using an expensive precision

resistor network. The INA2132 is available in the

SO-14 surface-mount package and is specified for

operation over the extended industrial temperature

range, –40°C to +85°C.

A single version of this product with similar specifications

is also available. See the INA132 data sheet

for details.
