Part of the Analog Circuits and Signal Processing book series (ACSP)


This chapter presents the design and implementation of a read-out IC that is intended for interfacing thermistor bridge, thermocouple, strain gauge and Hall sensors. The read-out IC consists of a current-feedback instrumentation amplifier (CFIA) and an analog-to-digital converter (ADC). The CFIA provides high input impedance for bridge read-out and also relaxes the ADC’s noise and offset requirements.
