ABSTRACT:
An integrate circuit companding amplifier for analog signals with digitally controlled gain. The expansion amplifier uses a square law with presentation of sign and the compression amplifier uses the inverse (square root law with preservation of sign). A digital potentiometer determines the gain, and peak detection plus feedback control of the potentiometer provides for automatic gain control. Three wire communication can program a fixed gain.
