CM32181A3OP - I2C Ambient Light Sensor

Download the CM32181A3OP datasheet PDF. This datasheet also covers the CM32181 variant, as both devices belong to the same i2c ambient light sensor family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • CM32181 is an advanced ambient light sensor with I2C protocol interface and designed by the CMOS process. It is easily operated via a simple I2C command. The active interruption feature within the threshold windows setting offers the benefit of eliminating loading of the controller monitor. CM32181 incorporates a photodiode, amplifiers and analog circuits into a single chip. The best spectral sensitivity is used to closely capture real human eye responses. CM32181 has excellent temperature comp.
