This schematic block features the VEML6046X00, a compact, automotive‑grade RGBIR color sensor designed for high-precision ambient light and color-temperature measurements. It integrates separate red, green, blue, and infrared photodiodes, a low-noise amplifier, and a 16-bit ADC, all in a tiny surface-mount package. With I²C communication and interrupt support, it enables robust color sensing, ambient brightness detection, and intelligent light-source differentiation.
The sensor’s wide dynamic range (0 to very high lux), excellent sensitivity, and separate IR channel make it ideal for applications behind dark cover glass or under challenging lighting conditions. The device is AEC‑Q100 qualified, supporting demanding environments such as automotive and industrial systems.
Key Features:
- Four-channel sensing: Red, Green, Blue, and Infrared
- 16-bit ADC resolution for precise measurement
- I²C digital interface with interrupt capability
- Wide ambient light detection range (very low to very bright)
- High sensitivity, enabling placement behind dark cover materials
- Supply voltage: ~2.5 V to ~3.6 V
- I²C bus voltage: ~1.7 V to ~3.6 V
- Low shutdown current (~0.5 µA) for power-efficient designs
- Operating temperature: –40 °C to +110 °C
- Compact SMD footprint: 2.67 mm × 2.45 mm × 0.6 mm
Typical Applications:
- Automotive display backlight control and white-point balancing
- Interior lighting systems and mood lighting
- Infotainment and instrument clusters requiring accurate color balancing
- Head-up displays and rearview mirror dimming
- Ambient light / color temperature sensing for smart lighting
- Color recognition and environmental light analysis
By integrating this Quickboards schematic block, engineers can rapidly prototype color-aware systems, achieve accurate light‑source characterization, and leverage a durable, production-ready sensor that excels even in demanding environments.
