Description



Features:

• Volume: Controls the left and right volume levels independently from 0 dB to 78 dB (in 2 dB steps) and dB (41 settings). Since the left and right levels are independent this circuit also functions as a balance control. 
• Fader: Attenuates either the rear or front outputs over 16 levels, from 0 dB to 20 dB in 2 dB steps, from 20 dB to 25 dB in 5 dB step, from 25 dB to 45 dB in 10 dB steps and then to 60 dB and dB.
• Bass/treble: Implements 21 position bass and treble controls with the addition of external capacitors.
• Input selector: Selects one of four inputs for both the left and right channels. The selected input signal can be amplified by between 0 dB and +18 dB in 6 dB steps.
• The provision of on-chip operational amplifiers means that few external components are required.
• Fabricated in a silicon gate process for minimal switching noise.
• All functions can be controlled by serial data over a CCB interface.
