Here is a close look at the common- versus differential-mode voltage and instrumentation amplifier (IA) topologies.
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 ...
Figure 1 shows a benign means of interfacing a low-level, wideband differential signal to an analog-to-digital converter (ADC). The FET input stage (AD8066) draws only 6 pA of input bias current and ...
