Original imported TA2022 dual-channel digital Class-T amplifier board 90W+90W

 

Product Details：

TA2022 is Tripath's analog input stereo integrated modulator and output stage. Its distinctive feature is that the chip is internally composed of an oscillator and a cmos tube, and externally combined with power inductors and high-speed diodes and other components to work. The modulator uses a spread spectrum switching mode instead of a fixed frequency, hence the company's name "Class T" amplifier. The TA2022 has 0.015% THD at 25W; 60-90W is a rise of 0.1%. It is packaged in a SSIP-32 plastic package and requires an external heat sink.

 

Brief introduction：

Using Tripath original imported TA2022

 

The front input capacitor and inter-stage coupling capacitor are imported from Germany Siemens capacitor 1UF, the main filter electrolytic capacitor is imported 3300UF/50V*2, and the rectifier is 10A rectifier flat bridge to ensure strong source of power support.

 

The resistor is selected with high precision, and the main circuit adopts high precision chip resistor with accuracy ±1%, which ensures good signal-to-noise ratio of the whole machine.

 

The PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, spray tin full process, to ensure the good performance of the size of the current through. The PCB quality, the production process.

 

The use of audio special high-current inductor, to ensure that the sound is crisp and powerful.

 

The sound quality is soft, dynamic and powerful, comparable to LM3886.

 

Basic parameters：

Voltage: AC24V-0-AC24V

 

Maximum power: 90W+90W

 

Size: 98MM*68MM*40MM high

 

Weight: 0.1KG

 

Note: This board does not include a heat sink, you need to add a small heat sink (0.1KG or so) attached to the metal side of the chip.  In addition, you need a section of 18650 battery, the negative terminal on the tail cap. (Please bring your own batteries, in order to smooth customs clearance, our goods are not equipped with batteries, thank you for understanding!)
