ISL29021 Digital Proximity Sensor with Interrupt Function The ISL29021 is an integrated proximity and infrared sensor with a built-in IR LED driver and I2C Interface (SMBus Compatible). This device provides infrared sensing to allow proximity estimation featured with interrupt function. For infrared and proximity sensing, an internal ADC has been designed based on the charge-balancing A/D conversion technique. The ADC is used to digitize the output signal from the photodiode array when the internal IR LED driver is turned on and off for the programmed time periods under user-selected modulation frequency to drive the external IR LED.
