high resolution conversion of light intensity to frequency • programmable colour and full scale output frequency • communicates directly with a microcontroller • single supply operation (2.7 V to 5.5 V) • power down feature • non-linearity error typically 0.2% at 50 kHz • stable 200 ppm/°C temperature coefficient, S0-S1: output frequency scaling selection inputs • S2-S3: photodiode type selection inputs • out pin: output frequency • OE pin: output frequency enable pin (active low), can be impending when using
