Product data sheet
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.

In accordance with the Absolute Maximum Rating System (IEC 60134).
