AD8231 is a digitally programmable instrumentation amplifier from Analog Devices. It features zero drift, high precision, wide dynamic range, large output swing, low power consumption, etc. It can be widely used in pressure and strain transducers, thermocouples and RTDs, programmable instrumentation, industrial controls, weighing scales, automotive controls, etc.
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, and the device includes an uncommitted op amp for additional gain or filtering.
