SAN JOSE San Jose, city, United States
San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. & SINGAPORE -- Avago Technologies Avago Technologies is an American company which was earlier the semiconductor products division of HP and later Agilent Technologies, before being spun off into a distinct legal entity. It holds more than 2,000 patents. (Nasdaq:AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today 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 Imagine feeding the output of a temperature sensor, which is in millivolts, to an Analog-to-digital converter to be processed. Is it possible for the Analog-to-Digital converter to process such a minute voltage amplitude? The answer is probably no. 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 One side of a bipolar transistor. See collector. ; and detector. The ambient light sensor, which has a spectral response The variable output of a light-sensitive device that is based on the color of the light it perceives. that is close to that of the human eye, is used to control display backlighting back·light

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 pulse width Pulse duration Cardiac pacing The duration of a pacing pulse in msecs , burst rate, duty cycle and frequency can be controlled to further minimize power consumption.
* Small form factor: L 4.95 by W 3.0 by H 1.45 mm
* Spectral responsivity close to that of the human eye
* Built-in LED and detector for proximity detection
* Low sensitivity variation across various light sources
* Output linearity across a wide illumination range
* Operational under strong sunlight and artificial light environments
* Adjustable LED driving current, pulse and burst parameters
* Controllable gain and integration time through external resistor resistor, two-terminal electric circuit component that offers opposition to an electric current. Resistors are normally designed and operated so that, with varying levels of current, variations of their resistance values are negligible (see resistance). and capacitor capacitor or condenser, device for the storage of electric charge. Simple capacitors consist of two plates made of an electrically conducting material (e.g., a metal) and separated by a nonconducting material or dielectric (e.g.
