GENERAL DESCRIPTION

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. The current sourced from the VAPD pin over a range of 5 nA to 5 mA is accurately mirrored with an attenuation of 5 and sourced from the IPDM monitor output. In a typical application, the monitor output drives a current input logarithmic amplifier to produce an output representing the optical power incident upon the photodiode. The photodiode anode can be connected to a high speed transimpedance amplifier for the extraction of the data stream.
