The device offers a move forward to a new level of performance not offered by another solution.
The ZXCW8100 operates in direct drive mode and can be selected to be with or without dead time.
Exceptional performance can be achieved with the ZXCW8100 device in direct drive mode, the dynamic range is 101dB, the noise floor sits at –125dB and when driving 1W into 4⍀ THD+N is 0.
021%.
The device supports all common digital audio input formats.
Sampling frequencies up to 192kHz are fully supported, dependant on which sampling frequency is selected then the device can operate in single, dual or quad speed modes.
In single speed mode, then the popular 44.
1kHz sampling from audio CDs is oversampled up to 76...
