This Design Idea offers a new instrumentation-amplifier topologythat improves ac CMR (common-moderejection). Because it uses discrete amplifiers,you can customize it for the lowestpower, price, noise, ...
The OP284 is a low noise dual op amp with a bandwidth of 4MHz and rail-to-rail input/output operation. These properties make it ideal for low supply voltage applications such as in a two op amp ...
