Intersil light and Proximity Sensors
Intersil's Optical Sensors are ideal for applications requiring optimized user experience and power savings. Our ambient light sensors can adjust a display’s backlight, which improves user experience and power savings by optimizing the display’s viewability. We can also sense proximity. For example, proximity sensors are often used to prevent accidental key activation in handheld display applications by disabling capacitive-touch buttons. Intersil’s Optical Sensors are best in class for ultra low light sensitivity, low power consumption, ideal spectral response, and easy to use simple output algorithms. Intersil offers a full suite of Optical Sensors to suit your applications requirements and budget.
Featured Products
ISL29028A
Low Power ALS & Proximity Sensor with Intelligent Interrupt and Sleep Modes
The ISL29028A is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C Interface (SMBus Compatible). This device uses two independent ADCs for concurrently measuring ambient light and proximity in parallel. The flexible interrupt scheme is designed for minimal microcontroller utilization.

ISL29023
Integrated Digital Ambient Light Sensor with Interrupt Function
The ISL29023 is an integrated ambient and infrared light to
digital converter with
I2C (SMBus Compatible) Interface. Its
advanced self-calibrated photodiode array emulates human
eye response with excellent IR rejection. The on-chip ADC is
capable of rejecting 50Hz and 60Hz flicker caused by artificial
light sources. The lux range select feature allows users to
program the lux range for optimized counts/lux.
