Abstract
An anti-clipping mixer circuit is provided within an integrated circuit. The mixer circuit allows for the independent level control of each input signal, thereby allowing the optimization of the signal-to-noise ratio. A master level control is provided to limit the overall combined output signal to a level below the operational amplifier's maximum voltage level. A control circuit may be used to automatically adjust the input signal levels as well as the combined output signal level.
