ISL29028IROZ-T7R5484 - Brand New RENESAS Optical Sensors - Ambient Light, IR, UV Sensors
-
Description
ISL29028IROZ-T7R5484 is a low power ambient light and proximity sensor with intelligent interrupt and sleep modes. It is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C interface. This component uses two independent ADCs to concurrently measure ambient light and proximity in parallel.
