The ADBS-A350 sensor is a small form factor (SFF) LED illuminated optical fi nger navigation system.
It is a low power optical fi nger navigation sensor with low-power architecture and automatic power management modes,making it ideal for battery-and power-sensitive applications such as mobile phones.
The ADBS-A350 is capable of high-speed motion detection – up to 20 ips. In addition, it has an on-chip oscillator and integrated LED to minimize external components.
The ADBS-A350 is based on Optical Finger Navigation(OFN) Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement.
The ADBS-A350 contains an Image Acquisition System(IAS), a Digital Signal Processor (DSP), and a communication system.
