研发客服Optical Finger Navigation (OFN) products from Avago Technologies offer a compact, precise, fast speed and highly reliable navigation solution, which will help enhance the overall system performance. Our OFN solution is user friendly and can be used in electronic devices such as mobile phones, MP3 players, ultra-miniature PCs, game pads, digital cameras and keyboards.
The ADBS-A350 sensor is a small form factor (SFF) LED illuminated optical finger navigation system. It is a low-power optical finger navigation sensor with low-power architecture and automatic power management modes, making it ideal for battery-and power-sensitive applications such as mobile phones.
There are no moving parts, thus provide high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.
The sensor is programmed via registers through either a serial peripheral interface or a two wire interface port. It is packaged in a 28 I/O surface mountable package.
The ADBS-A350 is designed for use with ADBL-A321 lens.The ADBL-A321 lens is the optical component necessary for proper operation of the sensor.
