光宝 LTR-579ALS-028

1. description
the ltr-579als-028 is an integrated low voltage i2c ambient light sensor (als), and a proximity sensor (ps), with built-in emitter ina 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 ambientbrightness. besides, with built-in proximity sensor, this sensor offers the feature to detect object at a user configurable distance.
the sensor has a programmable interrupt with hysteresis to response to events and that removes the need to poll the sensor for areading 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 endcustomers.
