ZSSC3026 Low Power 16 Bit Sensor Signal Conditioner IC
ZSSC3026 is a sensor signal conditioner integrated circuit for high accuracy amplification and analog-to-digital conversion of a differential input signal. Designed for high resolution altimeter module applications, the ZSSC3026 can perform offset, span and 1st and 2nd order temperature compensation of the measured signal. Developed for correction of resistive bridge sensors, it can also provide a corrected temperature output measured with an internal sensor.
Here is an excellent 2 minute YouTube video discussing applications for the ZSSC3026.
