Avago Technologies APDS-9801 Digital Proximity and Analog Ambient Light Sensor
The Avago Technologies APDS-9801 module integrates functions of an analog ambient light sensor and a digital proximity sensor. The Avago Technologies APDS-9801 is composed of four chips in one small package: ambient light sensor IC, proximity sensor signal conditioning circuitry, and a proximity sensor that includes both emitter and detector. The analog ambient light sensor has current output with spectral response close to the CIE standard photopic observer. The proximity sensor IC consists of an LED driver and receiver circuit with digital count output and featuring excellent ambient light cancellation capability. The combination of analog ambient light sensor and digital proximity sensor in one module makes the Avago Technologies APDS-9801 ideal for applications in portable devices such as mobile phones, PDAs, and notebooks.
