AD8231 Datasheet Digital Programmable Instrumentation Amplifier

Manufacturer: Analog Devices

Overview: Data Sheet AD8231 Zero Drift, Digitally Programmable Instrumentation.

General Description

The AD8231 is a low drift, rail-to-rail, instrumentation amplifier with software-programmable gains of 1, 2, 4, 8, 16, 32, 64, or 128.

The gains are programmed via digital logic or pin strapping.

The AD8231 is ideal for applications that require precision performance over a wide temperature range, such as industrial temperature sensing and data logging.
