We have tested the following configuration for the Differential-to-Single-ended conversion to the receiver output to support Headphones with Single-ended input ports.
Audio CODEC PDM Output -> RC Filters (8.2K, 1nF, two stages. See attached picture.) -> TPA6130A2
It worked, with the exception that the signal volume was kind of low.
Our CODEC was using about 4mA, which is good. However, the TPA6130was using about 300mA, which is way too high for our application.
Do you see any problem in the configuration or anything missing?
