Product Overview
The OPT3002 is a Texas Instruments light-to-digital optical sensor for measuring optical irradiance in the LED category. Its optical spectrum range is 300 nm to 1000 nm, with peak irradiance spectral responsivity at 505 nm under the stated datasheet test conditions. At 505 nm stimulus, the measurement range spans 1.2 nW/cm2 to 10 mW/cm2, supported by automatic gain ranging and a 23-bit effective dynamic range.
The device uses 12 binary-weighted full-scale range settings with less than 0.2% typical range matching. It supports continuous and single-shot measurement modes and communicates through an I2C and SMBus-compatible two-wire serial interface. Fast-mode I2C supports 0.01 MHz to 0.4 MHz SCL, while high-speed mode supports 0.01 MHz to 2.6 MHz.
OPT3002 operates from a 1.6 V to 3.6 V supply across -40°C to +85°C. The SDA, SCL, and INT pins are compatible with pullups from 1.6 V to 5.5 V. The DNP USON-6 package has a 2.00 mm x 2.00 mm x 0.65 mm body for compact optical sensor assemblies.
