Abstract
A common mode control circuit reduces abrupt voltage changes at the outputs of a pair of amplifiers which, in turn, reduces EMI and distortions that occur when the correlation between the signals fed to the four channels of an audio system diminishes. The common mode control circuit generates for each amplifier a reference potential that is a saturated replica of the respective differential input signal of the amplifier that saturates when the amplifier switches to a bridge configuration.
