PGA281 Datasheet (Texas Instruments) - Programmable Gain Instrumentation Amplifier

PGA281, Programmable Gain Instrumentation Amplifier

The PGA281 is a high-precision instrumentation amplifier with a digitally-controllable gain and signalintegrity test capability.

This device uses proprietary autozeroing techniques to offer low offset voltage, near-zero offset and gain drift, excellent linearity, and nearly no 1/f noise.
