The spectral response of the sensor – Rejects > 99% (typ) of IR tightly matches the photopic response of the human • Automatic Full-Scale Setting Feature Simplifies eye and includes significant infrared rejection. Software and Ensures Proper Configuration The OPT3001 is a single-chip lux meter, measuring • Measurements: 0.01 lux to 83k lux the intensity of light as visible by the human eye. The precision spectral response and strong IR rejection of • 23-Bit Effective Dynamic Range with the device enables the OPT3001 to accurately meter Automatic Gain Ranging the intensity of light as seen by the human eye • 12 Binary-Weighted Full-Scale Range Settings: regardless of light source. The strong IR rejection < 0.2% (typ) Matching Between Ranges also aids in maintaining high accuracy when industrial • Low Operating Current: 1.8 µA (typ) design calls for mounting the sensor under dark glass for aesthetics. The OPT3001 is designed for systems • Operating Temperature Range: –40°C to +85°C that create light-based experiences for humans, and • Wide Power-Supply Range: 1.6 V to 3.6 V an ideal preferred replacement for photodiodes, • 5.5-V Tolerant I/O photoresistors, or other ambient light sensors with • Flexible Interrupt System less human eye matching and IR rejection. • Small-Form Factor: 2.0 mm × 2.0 mm × 0.65 mm Measurements can be made from 0.01 lux up to 83k lux without manually selecting full-scale ranges 2 Applications by using the built-in, full-scale setting feature. This capability allows light measurement over a 23-bit • Display Backlight Controls effective dynamic range. • Lighting Control Systems The digital operation is flexible for system integration. • Tablet and Notebook Computers Measurements can be either continuous or single- • Thermostats and Home Automation Appliances shot. The control and interrupt system features • Point-of-Sale Terminals autonomous operation, allowing the processor to sleep while the sensor searches for appropriate • Outdoor Traffic and Street Lights wake-up events to report via the interrupt pin. The • Cameras digital output is reported over an I2C- and SMBus- compatible, two-wire serial interface. The low power consumption and low power-supply voltage capability of the OPT3001 enhance the battery life of battery-powered systems.
