AD7156BCPZ-REEL - Brand New Analog Devices ADCs/DACs
-
GENERAL DESCRIPTION
The AD7156 delivers a complete signal processing solution for capacitive sensors, featuring an ultralow power converter with fast response time.
The AD7156 uses an Analog Devices, Inc., capacitance-to digital converter (CDC) technology, which combines features important for interfacing to real sensors, such as high input sensitivity and high tolerance of both input parasitic ground capacitance and leakage current.
The integrated adaptive threshold algorithm compensates for any variations in the sensor capacitance due to environmental factors like humidity and temperature or due to changes in the
dielectric material over time.FEATURES
