Avago releases optical-navigation mouse sensors
Avago Technologies
ADNS-7700
Avago Technologies has introduced two new system-on-chip (SOC) Laserstream and LED optical-navigation sensors for use in USB-corded computer mice and a variety of other input-device applications.
The ADNS-7700 - which incorporates Avago's Laserstream navigation sensor, microcontroller and VCSEL illumination in a single chip - is suitable for designers of desktop PCs, trackballs and integrated input devices.
The ADNS-7700 is one of the first laser-navigation sensors in the industry with a microcontroller, navigation sensor and VCSEL integrated in a single package.
It is housed in a 22-pin staggered dual inline package (DIP) and can be used with either Avago's trim lens (ADNS-6180-001) or wide trim lens (ADNS-6180-002) to provide a complete navigation system.
This Laserstream-based navigation sensor operates on a single 5V power supply and meets USB 2.0 compliance.
Laser power is pre-calibrated prior to shipment.
Other key features include: high-speed motion detection of up to 45in per second (ips), acceleration of 20g and resolution up to 2400 DPI; a mechanical Z-Wheel interface for vertical and tilt-wheel scroll; on-the-fly resolution change; a keymap feature; and on-chip OTP memory for device-configuration flexibility.
The ADNS-5700 is a single-chip USB solution that integrates the optical navigation sensor with a microcontroller and LED driver to help simplify mouse designs.
Avago's ADNS-5700, which also operates on a 5V power supply, comes in an 18-pin optical package designed for use with Avago's round lens (ADNS-5100), trim lens (ADNS-5100-001) or truncated round lens (ADNS-5100-002).
With the addition of the ADNS-5200 clip and HLMP-ED80 LED, these parts provide a complete and compact optical-navigation mouse sensor.
This navigation sensor has no moving parts and doesn't need precision optical alignment, making the ADNS-5700 ideal for high volume assembly.
Other key features include: high-speed motion detection up to 30ips; accurate navigation over a variety of surfaces; and 12-bit motion reporting.
A reference-design kit, complete with sample navigation sensor and optical mouse, is available for the ADNS-5700 and ADNS-7700.
The optical mouse supplied with the kit enables input-device designers to evaluate the performance of the sensor prior to design.
A design guide included in the kit provides useful tips and information.
