DESCRIPTION

V+

The INA157 is a high slew rate, G = 1/2 or G = 2

difference amplifier consisting of a precision op amp

with a precision resistor network. The on-chip resis-

tors are laser trimmed for accurate gain and high

common-mode rejection. Excellent TCR tracking of

the resistors maintains gain accuracy and common-

mode rejection over temperature. The input common-

mode voltage range extends beyond the positive and

negative supply rails. It operates on ±4V to ±18V

supplies.

The difference amplifier is the foundation of many

commonly used circuits. The INA157 provides this

circuit function without using an expensive precision

resistor network. The INA157 is available in a SO-8

surface-mount package and is specified for operation

over the extended industrial temperature range, –40°C

to +85°C.
