Product Description
LTR-390UV-01 Ambient Light Sensor and Ultraviolet Light Sensor Description
The LTR-390UV-01 is an integrated low voltage I2C ambient light sensor (ALS) and ultraviolet light sensor (UVS) in a single miniature 2x2mm chipled lead-free surface mount package.This sensor converts light intensity to a digital output signal capable of direct I2C interface. It provides a linear ALS response over a wide dynamic range, and is well suited to applications under high 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.
LTR-390UV-01 Ambient Light Sensor and Ultraviolet Light Sensor Application
• Identifying the UV index in ambient light helps people to effectively protect themselves from sunburns, cancer or eye damage.
• To control brightness and color of the display panel in mobile, computing, and consumer devices.
LTR-390UV-01 Ambient Light Sensor and Ultraviolet Light Sensor Features
• I2C interface capable of Standard mode @100kHz or Fast mode @400kHz communication; 1.8V logic compatible
• Ambient Light / Ultraviolet light (UVS) Technology in one ultra-small 2x2mm ChipLED package
• Very low power consumption with sleep mode capability
• Operating voltage ranges: 1.7V to 3.6V
• Operating temperature ranges: -40 to +85°C
• Built-in temperature compensation circuit
• Programmable interrupt function for ALS , UVS with upper and lower thresholds
• RoHS and Halogen free compliant
• UVS/ALS Features
- 13 to 20bits effective resolution
- Wide dynamic range of 1:18,000,000 with linear response
- Close to human eye spectral response
- Automatic rejection for 50Hz/60Hz lighting flicker
LTR-390UV-01 Ambient Light Sensor and Ultraviolet Light Sensor Rating and Specification
Absolute Maximum Rating at Ta=25°C
Note: Exceeding these ratings could cause damage to the sensor. All voltages are with respect to ground. Currents are positive into, negative out of the specified terminal.
