STK3332 Description

Short technical summary and product information.

The STK3332 from SENSORTEK is a versatile integrated sensor combining ambient light sensing (ALS) and proximity sensing (PS) capabilities within a single package. It is designed for applications requiring robust backlight control and proximity estimation.

The ambient light sensor provides 16-bit digital output, with spectral response close to the human eye, suitable for a wide range of light intensities. The proximity sensor also offers 16-bit resolution and is optimized for 940nm infrared light, featuring a built-in IR LED driver with programmable current settings and noise cancellation.

This device operates within a voltage range of 1.7V to 3.0V and features excellent temperature compensation from -40°C to 85°C. It includes flexible interrupt settings for both ALS and PS functions, with intelligent persistence to optimize response times. The STK3332 utilizes an I2C interface for digital control and supports software shutdown mode for power saving.

Packaged in an OLGA form factor measuring 4.00mm x 1.50mm x 1.00mm, the STK3332 is designed for integration into mobile phones and smartphones. It is lead-free and RoHS compliant.
