ADJD-S313-QR999 Miniature Surface-Mount RGB Digital Color Sensor Data Sheet The ADJD-S313-QR999 is a cost effective, CMOS digital output RGB color sensor in miniature surface-mount package with a mere size of 5x5x0.75mm. The IC comes with integrated RGB filters, an analog-to-digital converter and a digital core for communication and sensitivity control. The output allows direct interface to micro-controller or other logic control for further signal processing without the need of any additional components. This device is designed to cater for wide dynamic range of illumination level and is ideal for applications like portable or mobile devices which demand higher integration, smaller size and low power consumption. Sensitivity control is performed by the serial interface and can be optimized individually for the different color channel. The sensor can also be used in conjunction with a white LED for reflective color management.

ESD Protection Diode Turn-On During Power-Up and Power-Down

A particular power-up and power-down sequence must be used to prevent any ESD diode from turning on inadvertently. The figure above describes the sequence. In general, AVDD and DVDD should power-up and powerdown together to prevent ESD diodes from turning on inadvertently. During this period, no voltage should be applied to the IO’s for the same reason.

Ground Connection

AGND and DGND must both be set to 0V and preferably star-connected to a central power source as shown in the application diagram. A potential difference between AGND and DGND may cause the ESD diodes to turn on inadvertently.
