NOA3301 - Digital Proximity Sensor

General Description

The NOA3301 combines an advanced digital proximity sensor and LED driver with an ambient light sensor (ALS) and tri- mode I2C interface with interrupt capability in an integrated monolithic device.

Key Features

  • and very low active sensing power consumption directly address the power requirements of battery operated mobile phones and mobile internet devices. The proximity sensor measures reflected light intensity with a high degree of precision and excellent ambient light rejection. The NOA3301 enables a proximity sensor system with a 32:1 programmable LED drive current range and a 30 dB overall proximity detection threshold range. The photopic light response, dark current compensation and high sensitiv.
