The INA128 devices belong to the group of high-class instrumentation amplifiers designed for extracting and amplifying weak, noisy signals from sensors and transducers. The main element of the instrumentation amplifier is the differential amplifier, which serves to amplify the useful differential signal and attenuate the harmful common-mode signal. The design of the system is based on three operational amplifiers and an internal network of resistors within a closed-loop feedback system. The gain is set using a single external resistor. Thanks to the use of laser technology in the input circuitry, excellent parameters have been achieved, such as: low input offset voltage, low temperature drift of offset voltage, and high common-mode rejection ratio (CMRR).
