Overview
CXA3271GE
Fingerprint Sensor
Description The CXA3271GE is an electrostatic capacitance method fingerprint sensor.
This monolithic IC integrates the sensor block, sense amplifier (3-bit gain adjustment), sample-and-hold, output amplifier and output buffer needed to acquire fingerprint images, as well as the timing generator for determining the operation of these functions onto a single chip.
