I have some questions for ADN2880 from customer.
Pad 4 and Pad 5 are described to connect to cathode of photo diode but the PD which the customer use can bonded just single wire. The customer would like to know which pad they should use and also would like to know another pad can be left ope.
In the data sheet, there is double wire are bonded from OUT and OUTB. Is this double wire bonding mandatory?
The rise time of output wave form is not good. Please see an attached picture. They confirmed the light source rise time is fast enough and guess it is from longer wire from PD to pad. However they ask ADI if ADI have any suggestion to improve this.
