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.
