Compensation Using a Suggested Set of Coefficients for Audio Effects Filter
Using the capless output configuration eliminates the need for these capacitors and removes the accompanying high-pass
filter entirely. However, this configuration does have one drawback – if the RETURN terminal of the headphone jack (which
is wired to the ’AIC26 VGND pin) is ever connected to a ground, that is shorted to the ’AIC26 ground pin, then the VGND
amplifier enters short-circuit protection, and the audio output does not function properly.
