... The TK2019 is a power (high current) amplifier that operates at relatively high switching frequencies. The output of the amplifier switches between VDD and GND at high speeds while driving large currents. This high-frequency digital signal is passed through an LC low-pass filter to recover the amplified audio signal ...

... The TK2019 is divided into two sections: the input section, and the output (high power) section. On the TK2019 evaluation board, the ground is also divided into distinct sections, one for the input and one for the output. To minimize ground loops and keep the audio noise floor as low as possible, the input and output ground must be only connected at a single point ...

... VPPSENSE and VNNSENSE pins. If the amplifier is powered up in the hysteresis band the TK2019 will be muted. Thus, the usable supply range is the difference between the over- voltage turn-off and under-voltage turn-off for both the VPP supply. It should be noted that there is a timer of approximately 200mS with respect to the over and under voltage sensing circuit ...

... TK2019 amplifier switching pattern will degrade the measurement. One feature of the TK2019 is that it does not require large multi-pole filters to achieve excellent performance in listening tests, usually a more critical factor than performance measurements. Though using a multi-pole filter may remove high-frequency noise and improve THD+N type measurements (when they are made with wide-bandwidth measuring equipment), these same filters degrade frequency response ...
