ADL5317 Datasheet (Analog Devices) - Avalanche Photodiode Bias Controller and Wide Range

ADL5317, Avalanche Photodiode Bias Controller and Wide Range

The ADL5317 is a high voltage, wide dynamic range, biasing and current monitoring device optimized for use with avalanche photodiodes.

When used with a stable high voltage supply (up to 80 V), the bias voltage at the VAPD pin can be varied from 6 V to 75 V using the 3 V-compatible VSET pin.
