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.
