OPT3001DNPR

The OPT3001DNPR from Texas Instruments is a digital ambient light sensor (ALS) that accurately measures visible light intensity, closely matching the human eye's photopic response. It features significant infrared rejection, ensuring accurate readings regardless of the light source and enabling mounting under dark glass for aesthetic purposes.

This sensor offers a wide measurement range from 0.01 lux to 83 k lux, with a 23-bit effective dynamic range and automatic gain ranging. It operates with a low current of 1.8 µA (typical) and supports a wide power-supply range of 1.6 V to 3.6 V. The device communicates via I2C and has a flexible interrupt system.

Designed for systems that create light-based experiences, the OPT3001DNPR is an ideal replacement for less precise sensors. Its spectral response tightly matches the human eye, and it rejects over 99% of IR light. The sensor is housed in a compact 2.0 mm x 2.0 mm x 0.65 mm USON package, suitable for surface mounting.

Key specifications include an operating temperature range of -40°C to 85°C, a wavelength sensitivity around 550nm, and 5.5-V tolerant I/O. The automatic full-scale setting simplifies software configuration and ensures proper measurements across its extensive dynamic range.
