Compensation Using Above 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 AIC28 VGND pin) is ever connected to a ground that is shorted to the
AIC28 ground pin, then the VGND amplifier enters short-circuit protection, and the audio output does not
function properly.
The AIC28 incorporates a programmable short-circuit detection/protection function. In case of short circuit, all
analog outputs are disabled and a read only bit D1 of control register 1DH/page 2 is set. In such cases, there
are two ways to return to normal operation:
Hardware or software reset
Power down all the output drivers, which can be achieved by setting bits D12, D11, D 8, D7, and D6 of control
register 05H/page 2 and then wait for driver power down status flags (bits D15D10 of control register
25H/page 2) to become 1. The wait time is typically less than 50 ms after which, output drivers can be
programmed as desired.
