LS521 ILLUMINATION-TO-DIGITAL CONVERTER

The LS521 is a low-noise, high-sensitivity and illumination-to-digital converter with two-wire SMBus serial interface. The device integrates a photodiode, a trans-impedance amplifier, and 8-bits analog-to-digital converter (ADC) in a single IC to provide illumination information over an effective 8-.

LS521 Features

* 1. Characterized with the C.I.E. response as the human eye’s response 2. 8-bit linear digital output for ambient illumination with two wire SMBus interface. 3. Tunable illumination sensitivity by an external resistor 4. Rejection of 50Hz/60Hz light ripple by an external resistor (RL) and an external
