PGA280 Datasheet (Texas Instruments) - Programmable Gain Instrumentation Amplifier

PGA280, Programmable Gain Instrumentation Amplifier

The PGA280 is a high-precision instrumentation amplifier with digitally-controllable gain and signal integrity test capability.

This device offers low offset voltage, near-zero offset and gain drift, excellent linearity, and nearly no 1/f noise with superior common-mode and supply rejection to suppo

PGA280 Features
