Fortunately, Intersil has solved this problem with the X9241
XDCPs. These devices can store the last position set by
control and automatically reload these values into the pot tap
registers upon power-up. Shown in the figure is the Intersil
X9241U quad 50KW XDCP used to control the treble, bass,
balance, and volume parameters of the LM1035 stereo
audio processor. Unlike a conventional DAC, the Intersil
devices can reload the last value, or a preset value, into the
tone/balance and volume registers upon power-up, so you
get predictable sound level conditions without any danger of
over-driving the power amplifier.
