8.2.1 Line Receiver for Differential Audio Signals in a Split-Supply System

The INA165x-Q1 are designed to require a minimum number of external components to achieve data sheet-level performance in audio line-receiver applications. Figure 53 shows the INA165x-Q1 used as a differential audio line receiver in split-supply systems that are common in many audio applications. The line receiver recovers a differential audio signal that may have been affected by significant common-mode noise.
