Rohm has a range of audio processors which it is targeting at car and home audio systems. 

The 18 ICs in the range offer a the different input and output configurations required to accommodate multiple audio sources and speakers.

There are also a number of acoustic correction options available. 

There include parametric equalisers, loudness circuits, and subwoofer LPF/HPFs that are designed to allow optimised audio playback based on vehicle cabin characteristics. 

A common register map is also included in all models, allowing control of the devices from most existing microcontroller software.

The distortion figure is 0.001%.
