AD8231 Digital Programmable Instrumentation Amplifier

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, s.
