The ADL5317ACPZ-REEL7 is a high voltage, wide dynamic range, Biasing and Current Monitoring IC 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 to 75V using the 3V-compatible VSET pin. The current sourced from the VAPD pin over a range of 5nA to 5mA 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.

• Accurately sets avalanche photodiode (APD) bias voltage wide bias range from 6 to 75V
