The LTR-X221A is a low power digital ambient light sensor (ALS) that measures the intensity of ambient light.

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 oper.
