The OPT4001 is a light to digital sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye. Specially engineered filter on the device rejects near-infrared component from the common light sources to measure accurate light intensity.

The OPT4001 is a single-chip lux meter, capable of accurately measuring the intensity of light as seen by the human eye regardless of light source. Output of OPT4001 is semi-logarithmic with 9 binary logarithmic full-scale light ranges along with highly linear response within each range, bringing capability to measure all the way from 312.5 µlux to 83 klux. This capability allows light sensor to have 28-bit effective dynamic range. With built-in automatic full-scale range selection logic users don’t have to select appropriate gain settings based on light levels.

The strong near-infrared rejection also aids in maintaining high accuracy despite placing the sensor under dark glass, which is common requirement from industrial design of end products due to aesthetics.

The OPT4001 is designed for systems require light level detection to enhance user experience and typically replaces low accuracy photo diodes, photo-resistors and other ambient light sensors with underwhelming human eye matching and near infra-red rejection.

OPT4001 device can be configured to operate with light conversion times all the way from 600µs to 800ms in 12 steps, providing system flexibility based on application need. Conversion time includes the light integration time and ADC conversion time. Resolution of the measurement is determined by the light intensity and the integration time, effectively bringing in capability to measure down to 312.5µlux of light intensity changes.

The digital operation is flexible for system integration. Measurements can be either continuous or triggered in one shots with register write. The digital output is reported over an I2C- and SMBus compatible, two-wire serial interface. An internal FIFO on output registers along with burst mode I2C support helps minimize interrupts and processing power required by the I2C controller.

The low power consumption and low power-supply voltage capability of the OPT4001 helps enhance the battery life of battery-powered systems.
