Product Overview
The OPT3001 is a Texas Instruments ambient light sensor for measuring visible illuminance over a 0.01 lux to 83 klux range. Its automatic full-scale setting and automatic gain ranging provide a 23-bit effective dynamic range, while the lowest full-scale range provides 0.01 lux LSB resolution.
The sensor is supplied in a DNP USON-6 package measuring 2.00 mm x 2.00 mm x 0.65 mm. Recommended operation is from -40°C to +85°C with a 1.6 V to 3.6 V supply. Digital I/O pins are 5.5 V tolerant, and the I2C pull-up supply range is 1.6 V to 5.5 V when VDD is less than or equal to VI2C.
OPT3001 uses precision optical filtering to match the human eye, with >99% typical infrared rejection and a 550 nm peak irradiance spectral responsivity under the stated test conditions. Interface pins include VDD, ADDR, SCL, INT, and SDA, with SCL, INT, and SDA using 10-kΩ pull-up connections to a 1.6 V to 5.5 V supply.
