TA2022 dual-channel T-class digital amplifier board

product Details

TA2022 is an analog input stereo integrated modulator and output stage produced Tripath. What makes it different is that the chip is used internally. It consists of an oscillator and a cmos tube, and works externally by combining power inductance, high-speed diode and other components. Its modulator adopts spread spectrum switching mode instead of fixed frequency, so the company is called "Class T" amplifier. Under the ± 33V power supply voltage, each channel can output 25W power on 8Ω load, and the idle loss power is measured as 3.4W. TA2022 has a 0.015% Gath at 25W; 60-90W increases to 0.1%. It is packaged in a SSIP-32 plastic package with a radiator.

Introduction:

n imported TA2022

n pre-input capacitor and inter-stage coupling capacitor adopt Siemens imported from Germany capacitor3.3UF, main filter electrolytic capacitor imported4700UF/50V * 2, rectifier adopts 25A rectifier flat bridge to ensure strong source the constant power support of the source.

n high-precision resistance is selected for resistance, and high precision of ± 1% is adopted for main circuit. Degree patch resistor ensures good signal-to-noise ratio of the whole machine.

n PCB adopts 1.6mm thick double-sided plate, 2.0 oz copper thick, tin spraying all work art ensures good passing performance of large and small current. PCB quality and manufacturing process.

n the audio special high current inductance is adopted to ensure the sound is crisp and powerful.

n the sound quality is soft, beautiful and powerful, which is comparable to lm3886.
