Product Announcement from Avago Technologies
Avago Technologies ADNS-2700 USB small form factor mouse sensor is a System-on-Chip (SoC) optical sensor with the worlds lowest pin count. Suitable for use in mice, trackballs and other human interface devices (HID), the compact ADNS-2700 optical sensors help eliminate the need for an external microcontroller and require the use of fewer passive components. The highly-integrated LED-based optical sensors also help deliver ease-of-design and lower overall system costs.
The ADNS-2700 optical sensor contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP) and a USB stream output in a small-footprint 8-pin dual in-line package (DIP). With an integrated oscillator and pull-up resistor, the optical sensor further reduces external component count. The optical sensors do not require precision optical alignment, which also helps facilitate high-volume assembly. On-chip One-Time-Programming (OTP) memory enables designers to program their own product ID (PID) and vendor identification (VID) information and to select the resolution setting and sensor orientation without any need for a software driver, providing streamlined customization.
Avagos ADNS-2700 optical sensors provide precise, high-speed tracking for mice with best-in-class motion detection of up to 30 inches per second (ips) and 8g acceleration detection. The programmable resolution ranges from 250 up to 1250 counts per inch (cpi) for highly accurate, sensitive navigation.
