Abstract
A dual channel DC controllable tone, volume, and balance control IC is described. A novel variable response filter, combined with a time constant control technique, makes it possible to integrate all functions into a 16-pin package. The chip, requiring very few external components, has an 80 dB gain controlling range and less than 0.2 percent total harmonic distortion.
