NOA3315
Digital Proximity Sensor with Dual Ambient Light Sensors and Interrupt
Description The NOA3315 combines an advanced digital proximity sensor and
LED driver with dual ambient light sensors (ALS) and tri−mode I2C interface with interrupt capability in an integrated monolithic device. Multiple power management 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 NOA3315 enables a proximity sensor system with a 16:1 programmable LED drive current range and a 30 dB overall proximity detection range.
