Programmable Gain Instrumentation Amplifiers for Sensor Applications
The ISL2853x and ISL2863x zero-drift amplifiers feature an integrated RFI filter for EMI reduction and a gain stage output that provides flexibility for more complex designs like ECG.
Micropower, Rail-to-Rail I/O Instrumentation Amplifier
The EL8170 instrumentation amplifier is optimized for single supply operation over the +2.4V to +5.5V range, offers 95µA maximum supply current and is compensated for a gain of 100 or more.
Instrumentation amplifiers are precision, integrated operational amplifiers that have differential input and single-ended or differential output. Some of their key features include very high common mode rejection ratio (CMRR), high open loop gain, low DC offset, low drift, low input impedance and low noise. Programmable gain instrumentation amplifiers are specialized in-amps that have fixed gain levels. The appropriate gain level is selected by digital means.
