Avago Technologies (Nasdaq:AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, announced a new ambient light and proximity sensor that has been integrated into an ultra-thin module for use in mobile phones. Avago’s compact APDS-9800 integrated sensor module is designed to help conserve power and extend battery life in mobile phones and is easy to install. This new sensor module can also be used in other mobile electronic applications such as PDAs, handheld games and personal computers.
Built in a surface mountable package that is 1.45 mm thick by 4.95 mm in length by 3.0 mm wide, the APDS-9800 offers many technical features that are required by mobile phone manufacturers such as an extended detection range, and signal conditioning circuitry which offers superior performance in bright sunlight conditions. The APDS-9800 is composed of four chips: an ambient light sensor IC; proximity sensor and signal conditioning IC; LED emitter; and detector. The ambient light sensor, which has a spectral response that is close to that of the human eye, is used to control display backlighting brightness. The proximity sensor signal conditioning IC consists of an LED driver and receiver circuit with excellent ambient light cancellation capability. The built-in LED and detector allow the sensor to detect the proximity of an object to the device.
Avago’s APDS-9800 includes a shutdown mode to conserve power consumption and extend battery life. Additionally, the pulse width, burst rate, duty cycle and frequency can be controlled to further minimize power consumption.
