OPT3007YMFR

The OPT3007YMFR from Texas Instruments is a single-chip lux meter designed to measure visible light intensity as perceived by the human eye. This ambient light sensor (ALS) is available in an ultra-small PicoStar package, making it suitable for space-constrained applications. It features a precision spectral response that closely matches the photopic response of the human eye, coupled with strong infrared rejection to ensure accurate measurements regardless of the light source. The device operates over a wide temperature range of -40°C to +85°C and supports a power supply range of 1.6V to 3.6V.

Key features include automatic full-scale setting, allowing measurements from 0.01 Lux up to 83k Lux without manual range selection. It boasts a 23-bit effective dynamic range and 12 binary-weighted full-scale range settings with typical matching below 0.2%. The OPT3007YMFR consumes a low operating current of 1.8 µA (typical) and utilizes an I²C interface with a fixed address, simplifying connections to four pins. Its small form factor, measuring 0.856mm x 0.946mm x 0.226mm, and 5.5V tolerant I/O further enhance its design flexibility. This sensor is an ideal replacement for photodiodes, photoresistors, or lower-performing ambient light sensors in applications requiring accurate light measurement, such as in conjunction with backlight ICs or lighting control systems.
