Our customer is developing an oximeter with ADPD1081, he is planning to use a standard Omeda probe.
On this type of probe the photodiode cathode is connected to GND (shield). On ADPD1081 block diagram, we see that the photodiode cathode is connected to PDC pin.
Customer would like to know if its possible to connect PDC pin to GND (through Omeda probe). On the datasheet I see that PDC pin can assume different voltage values (from 1v8 to 0v) depending on the value of register 0x54, in this case I would like to know if is there a workaround to allow the use of standard Omeda probes.
Thank you in advance,
