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.
