Hi Sirs,
As a following of the previous thread at https://e2e.ti.com/support/audio/f/audio-forum/974236/tpa2011d1-tpa2011-input-mixer-circuit-review
We calculated the impedance matching after DC block capacitors: R9=R3//R6//R8//R6~=39kR, C9=C3//C6//C7//C8~=0.22uF
However, should we take account of the low pass filter circuit R1, R2, C1, C2 and R4, R5, C4, C5 to avoid pop noise during power up.
Would you please provide tips how to calculate and optimize the component values to minimize pop noise during power up?
Thank you and Best regards,
Wayne Chen
