DESCRIPTION

· The OPT3007 is a single-chip luxmeter designed to measure visible light intensity as perceived by the human eye.

· It features an ultra-small PicoStar package, making it suitable for compact spaces.

· The device has a fixed addressing scheme, requiring only four pins for operation, which aids in PCB design by allowing a larger opening to the active sensor area.

· It includes precision spectral response matching the human eye's photopic response and strong IR rejection for accurate light intensity measurements under various light sources and conditions.

FEATURES

· Precision optical filtering matches the human eye and rejects over 99% of IR.

· Automatic full-scale setting feature for measurements from 0.01 Lux to 83k Lux.

· 23-bit effective dynamic range with automatic gain ranging.

· 12 binary-weighted full-scale range settings with less than 0.2% matching between ranges.

· Low operating current of 1.8µA typical.

· Wide operating temperature range from -40°C to +85°C.

· Wide power-supply range from 1.6V to 3.6V.

· Fixed I2C address and 5.5-V tolerant I/O.

· Small form factor: 0.856-mm × 0.946-mm × 0.226-mm PicoStar™ package.

APPLICATIONS

· Smart watches and wearable electronics.

· Health fitness bands.

· Display backlight controls.

· Lighting control systems.

· Tablet and notebook computers.

· Cameras.
