OFP100-B Sensor

OFP100-B finger print image sensor 

The OFP-100 fingerprint image sensor is based on capacitive-contact technology with hardened surface and enhanced ESD resistivity. The build-in analog and digital circuitry minimizes the number of external component, and provides easy-to-use, standard SPI interface to microprocessors.

The operation of OFP-100 is controlled through registers, following a simple protocol. The captured image quality can be adjusted by setting gain, offset or reference voltage parameters. The internal operation and interface speed can also be configured to the need.
