8 Summary

The TLV320ADCx120 and PCMx120-Q1 family of devices offers very flexible input configuration making it suitable for a wide range of applications. Multiple common-mode tolerance modes are provided to allow the system to perform well even in the presence of large amounts of common-mode noise. Since the performance of the devices does change with the input configuration, it is recommended to use the lowest common-mode setting possible that still satisfies the tolerance required by the system. For best performance, AC coupling is recommended with DRE enabled and the lowest input impedance setting that can be used.
