DESCRIPTION

· The OPT3004 is a single-chip lux meter designed to measure visible light intensity, closely matching the human eye's photopic response.

· It features precision spectral response and strong IR rejection, ensuring accurate light measurement across various light sources.

· The sensor is ideal for systems creating light-based human experiences, replacing less accurate photodiodes or photoresistors.

· It operates over a wide range from 0.01 lux to 83 k lux, utilizing a 23-bit effective dynamic range with automatic full-scale setting.

FEATURES

· Precision optical filtering matches human eye response, rejecting over 99% of IR at ±85° incidence.

· Automatic full-scale setting simplifies software integration and ensures proper configuration.

· Low operating current of 1.8 µA and wide power supply range from 1.6 V to 3.6 V.

· Operates in temperatures from -40°C to +85°C and includes a flexible interrupt system.

· Available in small form factors: 2 mm × 2 mm × 0.65 mm (USON) and 2.1 mm × 1.9 mm × 0.6 mm (SOT-5X3).

APPLICATIONS

· IP Network cameras and display backlight controls.

· Lighting control systems and tablet/notebook computers.

· Thermostats, home automation appliances, and point-of-sale terminals.

· Outdoor traffic and street lights.
