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.

Features
• Electrostatic capacitance type sensor (charge transfer method)
• Number of pixels: 192 × 128
• 317 DPI
• Low power consumption (50mW or less)
• Single 3.3V power supply
• Sensor gain control: 3 bits
• S/N ratio improved by on-chip sensor block parasitic capacitance cancel function

Applications
    Fingerprint verification units
