... A C Charge pump input capacitor. This capacitor should be connected directly between D pins 2 (DCAP2) and 3 (DCAP1) and located physically close to the TA2024B. C Charge pump output capacitor that enables efficient high side gate drive for the P internal H-bridges. To maximize performance, this capacitor should be connected directly between pin 36 (CPUMP) and pin 33 (VDDA) ...

... TA2024B output pins is to reduce the trace length of the switching outputs. This will aid in reducing radiated emissions. Please see the External Component Description section on page 6 for more details on the above- mentioned components. The Application/ Test Circuit refers to the low side diodes as D ...

... Copper Area (square inches) In the above graph Copper Area is the size of the copper pad on the PC board to which the heat slug of the TA2024B is soldered. The heat slug must be soldered to the PC Board to increase the maximum power dissipation capability of the TA2024B package. Soldering will minimize the likelihood of an over-temperature fault occurring during continuous heavy load conditions. The vias used for connecting the heatslug to the copper area on the PCB should be 0.013” ...

... Tripath amplifiers switching pattern will degrade the measurement. One feature of the TA2024B 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 ...

... The package for the TA2024B is a 36-Lead Power Small Outline Package (PSOP), similar to JEDEC outline MO-166, variation AE. Tripath currently has two suppliers for this package. We recommend that the exposed copper heatslug width for the PCB design be at least 7.3mm wide to accommodate the heatslug width variation for each package ...
