I am trying to connect a photodiode to the ADL5304-EVALZ.
According to Figure 12 in UG-339 (http://www.analog.com/media/en/technical-documentation/user-guides/UG-339.pdf) the cathode of the photodiode must be conencted to pin 1 of P3.
Pin 1 is connected to INUM.
If I look at the datasheet of ADL5304 (http://www.analog.com/media/en/technical-documentation/data-sheets/ADL5304.pdf), figure 55 shows a photodiode connected with the anode to INUM.
I am confused, could please someone clarify this to me?
As additional information:
- I am working with a single supply, the jumper P1 is set
- R5 is NOT populated, R15 is 100R (I am not using adaptive bias)
- The other resistors for slope and intercept are as delivered (R24 and R25 are 0, everything else is open)
I would connect the photodiode with the anode to INUM and the cathode to 2VLT. Is that correct?
