ISL76682中文资料Automotive Low Power, High Sensitivity, Light-to Digital Sensor With I²C Interface数据手册Renesas规格书

描述 Description

The ISL76682 is a low power, high sensitivity, integrated light sensor with I²C (SMBus Compatible) interface. Its state-of-the-art photo-diode array provides close-to human eye response and good IR rejection. This ADC is capable of rejecting 50Hz and 60Hz flicker caused by artificial light sources. The lux range select feature allows you to program the lux range for optimized counts/lux.
In normal operation, typical power consumption is 55μA. To further minimize power consumption, two power-down modes have been provided. If polling is chosen over continuous measurement of light, the automatic power-down function shuts down the whole chip after each ADC conversion for the measurement. The other power-down mode is controlled by software using an I²C interface. The power consumption can be reduced to less than 1μA when powered down. Operate on supplies from 2.25V to 3.3V with an I²C supply from 1.7V to 3.6V, the ISL76682 is specified for operation across the -40°C to +105°C ambient temperature range.
