AFE4405: Read data from the PD1 and from the PD2 separately

Quentin Fleury

Part Number: AFE4405

Hi,

On the AFE4405, I saw it's possible to connect 2 photodiodes (PD), but in the datasheet I did not see anything about how to read data from the PD1 and from the PD2 separately.

Please, could you tell me if it's possible to do that ? And if yes how I can do this operation.
Thank you in advance,

Best regards,

Hello Quentin,

You may refer to Table 34 for selecting the PD in a static manner or Figure 50 for a timing scheme for the dynamic selection of the dual PD within the PRF cycle.

Please refer to section 8.4.8 in the datasheet for further details about the dual PD mode.
