Description
The LTR-578ALS-01 is an integrated low voltage I2C ambient light sensor (ALS), and proximity sensor (PS), with built-in emitter in a single miniature chipled lead-free surface mount package.
The ALS provides a linear response over a wide dynamic range, which is well suited to applications under very low or bright ambient brightness. Besides, with built-in proximity sensor, this sensor offers the feature to detect object at a user configurable distance.

FEATUREs
• I2C interface (Standard mode @100kHz or Fast mode @400kHz)
• Ambient Light and Proximity Sensing in one ultra-small ChipLED package
• Very low power consumption with sleep mode capability
• Operating voltage ranges: 1.7V to 3.6V
• Operating temperature ranges: -40 to +85 ºC
• Built-in temperature compensation circuit
• Programmable interrupt function for ALS and PS with upper and lower thresholds
• RoHS and Halogen free compliant

ALS Features
➢ 16 to 20 bits effective resolution
