The NAU83G10VG is a mono Class D audio amplifier with integrated Klippel Controlled Sound (KCS) technology based on the nonlinear mirror filter and current sensing for speaker parameter identification. The adaptive, nonlinear control system cancels the DC displacement, harmonic and intermodulation distortion generated by speaker nonlinearities, operates the voice coil at the optimum rest position and compensates for speaker parameter variation due to aging and climate changes. The new hardware and software capabilities in the NAU83G10VG allow to safely operate smaller speakers at the physical limits to generate more acoustical output at higher sound quality while providing reliable protection against thermal and mechanical overload compared to conventional linear algorithms.

The NAU83G10VG operates with analog supply voltages from 1.6V to 1.98V, while the battery supply voltage can operate from 2.9V to 5.5V.  The operating temperature range is specified from -40°C to +85°C, and it is available in CSP 50 Ball package with a 0.5mm pitch.
