Other Parts Discussed in Thread: PCM1861, PCM1860
Hello All,
Is the +12dB gain from using Diff ch 2 in addition to the 32dB (26 in diff mode) from the PGA? Also the PGA section (8.8) of the datasheet seems to state the maximum gain is 32dB but the register mapping states 40dB.
For some background, I am interfacing a condenser mic and need as much gain as possible so any suggestions are welcome.
Also does TI have a reference schematic for phantom power to be used with the PCM186x range of devices?
Regards
GD
