High Speed FET Input Instrumentation Amplifier with Low Input Bias Current and High AC Common-Mode Rejection

Circuit is a high speed FET input, gain of- 5 instrumentation amplifier (in-amp) with a wide bandwidth (35 MHz) and excellent ac common-mode rejection, CMR, (55 dB at 10 MHz). The circuit is ideal for applications where a high input impedance, fast in-amp is required, including RF, video, optical signal sensing and high speed instrumentation. The high CMR and bandwidth also makes it ideal as a wideband differential line receiver
