Low Power, High Sensitivity, I²C Ambient Light Sensor

Features

• Designed using CMOS process technology, the VEML32186 is an advanced ambient light sensor featuring an I2C protocol interface. It is easy to operate via simple I2C commands.
• Incorporating a photodiode, amplifiers, and analog circuits all within a single chip, it achieves spectral sensitivity optimized to closely match the response of the human eye.
• Offering excellent temperature compensation, the VEML32186 also features a robust refresh rate setting that eliminates the need for an external RC low pass filter. A software shutdown mode reduces power consumption to less than 1 μA.
• Package type: surface-mount
• Dimensions (L x W x H in mm): 2.35 x 1.8 x 1
• Integrated modules: ambient light sensor (ALS)
• Supply voltage range VDD: 1.7 V to 2.0 V
• Low operating current: 40 μA (typ.)
• Communication via I2C interface
• Inter feature (INT) support
• Floor life: 168 h, MSL 3, according to J-STD-020
