× 40 W/2 Ω stereo BTL car radio power amplifier

7.6 Differential inputs

The input stage is a high-impedance fully differential balanced input stage that is also

capable of operating in a single-ended mode with one of the inputs capacitively coupled to

an audio ground. It should be noted that if a source resistance is added (input voltage

dividers) the CMRR degrades to lower values.
