Introduction

The LTR- 381RGB- 01 is an integrated low voltage I2C ambient light sensor (ALS) and a color sensor (CS) in a single 2x2mm miniature ChipLED lead- free surface mount package. With the advanced RGB color sensor, this sensor converts light (Red, Green, Blue, and IR) intensity to a digital output signal capable of direct I2C interface. The ALS provides a linear response over a wide dynamic range, which is well suited to applications under very low or bright ambient brightness. The sensor has a programmable interrupt with hysteresis to response to events and that removes the need to poll the sensor for a reading which improves system efficiency. This CMOS design and factory- set one time trimming capability ensure minimal sensor- to- sensor variations for ease of manufacturability to the end customers.
