... The TK2070 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 ...

... MCP101-450 from Microchip Corporation has been used by Tripath to implement clean power up/down operation. If turn-on and/or turn-off noise is still present with a TK2070 amplifier, the cause may be other circuitry external to the TK2070. While the TK2070 has circuitry to suppress turn-on and turn-off transients, the combination of power supply and other audio circuitry with the TK2070 in a particular application may exhibit audible transients ...

... TK2070 amplifier switching pattern will degrade the measurement. One feature of the TK2070 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 ...
