• ADL5317 Voltage Noise

    I have an APD that requires a modestly tight voltage ripple on the cathode. I am considering using the ADL5317.

    Is there a spec for voltage ripple on the VAPD pin? Similarly, is there a PSRR spec for the VPHV pin to the VAPD pin.

    Furthermore, Mouser seems…

  • ADL5317 was burned!

    A few days ago,I applyed some samples of ADL5317ACPZ-REEL7. Then I test it with the circuit come from the datasheet.At the first time,I used 71V to supply pin 4(pin VPHV). The chip was burned from pin 4. Then I tested another time today. I supplyed pin…

  • ADL5317 + Ad8304 Silicon photomultiplier current mirror

    Would be possible to use the ADL5317 + Ad8304 as a Silicon photomultiplier (SiPM) current mirror? I use the Hamamatsu MPPC for low light levels. The MPPC Vbias is 74V aprox. and typically the current of the MPPC is lower than 50 nA.

  • RE: ADL5304 current direction

    Hi mwee2020,

    You might look at the Current Mirror products, ADL5315 or the high voltage version, ADL5317 designed for APDs. Each part has an App Note showing typical usage.    -BruceH

  • RE: ADL5315

    You may damage the part if you force current into the input pin.  The output will not pull current into the output in this situation.

    We only have the ADL5315 and ADL5317.  Neither of which function as you describe.

  • RE: ADL5304 with negative current

    No, this won't work, current needs to flow into the collector of the measurement/reference transistor for the ADL5304 to work correctly.

    Have you looked at using one of the current mirrors, ADL5315 or ADL5317, to reverse the polarity of the current…

  • RE: SIPM preamplifier

    Hello lolomontp,

    I'm not aware of any ADI-specific chips for SiPM support. Perhaps some other readers could advise if known.

    ADL5317 is intended for APD biasing over a wide optical power range, and also provides a monitor output. The product page…

  • RE: LT3571 APD Bias circuit

    The LT3571 is used to generate a bias voltage for the APD diode. From the schematics shown on the datasheet it seems this is used for DC level power sensing and to control it's gain but not necessarily as a fiberoptic data receiver.

    I assume you…
