hi  experts,

Im looking for solution on working of pga 309 . I have dumped the example eeprom  Data to the At24c04 eeprom ic  as mentioned Table A-2.  and also used the circuit diagram as in Figure A-1. but i  cannot measure the out put voltage by varying the potentiometer, output voltage remains at Zero voltage

hoping to get solutions,

thanks,

    Hello Selvam,

    What are you using to digitally communicate with the PGA309 and EEPROM?

    Can you provide a readout of your EEPROM data, including the Checksums? With the EEPROM improperly connected, or with an incorrect checksum, the PGA309 will not start up and VOUT will not be enabled.

    Best regards,
