LTR-X221A Datasheet | LITEON

features enhanced IR rejection capability. The LTR-X221A also incorporates an IR channel with peak response at 850nm and can function as 850nm IR metering. The LTR-X221A’s ultra-sensitive ALS photodiode enables high accuracy metering with short integration time under low lux environment, which allows the use of high transmission attenuation cover material for aesthetics industrial designs. In addition, the operating range can be easily extended to over 35K lux when low gain mode is used. The digital operation modes are flexible for system integration. Measurements can be performed with either single or continuous mode. The highly configurable interrupt system enables the sensor to trigger the host system to read out the data through 2-wire serial interface only when the pre-defined conditions are met, hence allowing the host system to sleep or reducing the host system’s load. The LTR-X221A features wide operating range patible with both 1.8V and 3V systems. The low power consumption helps to enhance the battery life and is well suited for battery-operated systems.
