I want to find a solution for biasing in APD systems. APD has  characteristic:
temperature coefficient and noise of dark current are large.


1.       You can use our ADN8831 and a TEC module to control/fix the APD die to
a pre-set temperature. So, the temperature coefficient related issue been
2.       Dark current usually been determined by process, and by temperature.
With the solution recommended above, customer’s problem  changed to select a
right APD die product (with right process).

So, it looks like the temperature control might be the right solution.
