TIOPT3001DNPR
Overview
The OPT3001DNPR is a high-precision digital ambient light sensor (ALS) designed to mimic the spectral response of the human eye. It features a wide dynamic range from 0.01 lux to 83 k lux with an integrated 23-bit effective dynamic range through automatic gain ranging. Operating on a supply voltage of 1.6V to 3.6V, it is optimized for low-power systems with a typical operating current of only 1.8 microamps.
Why Choose This Part
This sensor excels due to its precision optical filtering that effectively rejects more than 99 percent of infrared light, ensuring accurate measurements regardless of the light source. The automatic full-scale setting simplifies software development by eliminating the need for manual range selection, while the extremely low shutdown current of 0.3 microamps makes it ideal for battery-operated devices.
Applications
Key Specifications
Getting Started
Engineers can evaluate this sensor using the OPT3001EVM evaluation module. Communication is handled via a standard I2C or SMBus interface, and the device includes a flexible interrupt system to notify the host processor when light levels exceed or fall below user-defined thresholds.
