CXA3621GE Description
The CXA3621GE is an electrostatic capacitance method fingerprint sensor. This monolithic IC integrates the sensor block, sense amplifier (3-bit gain adjustment), sample-andhold, 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.
