Texas Instruments TPA2038D1: When using the TPA2038D1, what is the recommended input capacitor value (for PopNoise countermeasures)?

amplifier/linear

In general, the larger the capacitance of the capacitor, the more pop noise occurs, so although it depends on the band, the smaller the capacitor, the better. Therefore, please check the default setting of 0.01uF with EVM first.

Also, I have two additional points.
・Since it basically depends on the cutoff, the smaller the capacity, the smaller the PopNoise.
・If the time constant changes between differential inputs, pop noise will occur at startup, so it is recommended to use the same capacitance on the C-connection side of GND.
