Avago2.4G无线/有线LED光学鼠标设计分享

ADNS-7050介绍：

       Avago公司的ADNS-7050（ADNS-7050数据手册）光学传感器是基于新的LaserStream技术，包括图像采集系统（IAS），数字信号处理器（DSP）和一个四线串口。ADNS-7050传感器的工作电压为2.7V-3.6V，并可自我调节，还具备延长电池使用寿命的节电模式。它可以实现每秒高达20英寸的移动探测能力、高达8G的加速度及可选的每英寸400和800cpi的分辨率。可广泛应用在激光鼠标，光学跟踪球，综合输入设备和以电池为能源的输入设备。

ANDS-7050应用：

Laser mice
Optical trackballs
Integrated input devices
Battery-powered input devices
The ADNS-7050 sensor along with the ADNS-6120 or ADNS-6130-001 lens, ADNS-6230-001 clip and ADNV-6340 VCSEL form a complete and compact laser mouse
tracking system. There is no moving part, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.
