简介
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.

Another area that Intersil has ICs is ambient light sensors. In the past, we've had a large market share in portable devices like handsets, cell phones, cameras, etc. with our ambient light sensors. These devices are now migrating into the vehicle. So, there's a few key areas that they're used. They're used for adjusting the brightness on the lighting on your dashboards. They're also used within the mirrors in the vehicle where there is a sensor at the back of the mirror and a sensor now in the front of the mirror, where you actually, you detect the difference in light coming from headlights before you or from behind you. So, our ambient light sensors are designed specifically to meet automotive requirements. We are the only ambient light sensor supplier worldwide that meets the full requirements up to a 105 °C for our ambient light sensor packaging. All our competitors, the best they can get is up to 85 °C.
So, if you have an application where your ambient light sensor is on your dashboard or at the back of the mirror, overtime that will degrade with performance if it's only rated to 85 °C. So, our devices today are the only ones in the market rated to actually meet that requirement.
