APDS-9250 Digital RGB, IR, and Ambient Light Senso

The Broadcom APDS-9250 is a low-voltage digital RGB, IR, and ambient light sensor device that converts light intensity to a digital output signal. The device supports the I²C bus interface and has a programmable interrupt controller that takes minimal microcontroller (MCU) resources. The color-sensing feature is useful in applications such as LED RGB backlight control, solid-state lighting, reflected LED color sampler, and fluorescent light color temperature detection. With the IR sensing feature, the device can be used to read the IR content in certain lighting conditions and detect the type of light source.

Features
  • Miniature package size: 2.00 mm x 2.00 mm x 0.65 mm (L x W x H)
  • Up to 20-bit resolution
  • I²C-compatible interface with dedicated interrupt pin
  • Individual channels for red (R), green (G), blue (B), and infrared (IR)
  • Approximate human eye response with green channel
  • Precise light intensity measurements under diverse lighting conditions and various attenuation materials, including dark glass
  • ALS and RGB sensing with integrated IR-blocking filter
  • Specially-designed matrix arrangement of photodiodes to have optimal angular response
  • Low power consumption: 1 µA typical in standby mode
Applications
  • OLED display control
  • RGB LED backlight control
  • Ambient light color temperature sensing
