Avago Technologies Launches Ultra-Thin Integrated Optical Proximity Sensor for Mobile Electronic Applications



New Proximity Sensor Features Built-In Signal Conditioning and Space-Saving Packaging Technology for Easy Design Implementation

SAN JOSE, CA, and SINGAPORE, June 29, 2009 -- Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced a new ultra-thin integrated optical proximity sensor for use in a wide range of portable consumer electronic devices, and personal computers. Avago's APDS-9120 proximity sensor combines a built-in signal conditioning IC, emitter and detector into a single package which offers both analog and digital output options for easy installation. This proximity sensor is ideal for use in mobile phones, PDAs, handheld games, and notebook computers.

With a surface mountable package size that is 1.1 mm thick by 4.4 mm by 4.4 mm, the APDS-9120 offers many technical features required by mobile phone manufacturers such as an extended detection range, and superior signal conditioning circuitry which offers superior performance in bright sunlight conditions. Additionally, this integrated proximity sensor is very robust and provides application designers with ease of implementation as it eliminates the need for an external LED driver, signal filtering and amplification, as well as sunlight and ambient light immunity. This sensor also incorporates a stuck high protection circuit to preserve LED life.

Competitively priced, the APDS-9120 includes a shutdown mode to conserve power consumption and extend battery life in portable devices. Additionally, the pulse width, burst rate, duty cycle and frequency can be controlled to further minimize power consumption. Moreover, with an external limiting resistor, the LED current of this optical proximity sensor can be configured to a variety of levels.
