TPA3001D1 Power Amplifier
Recently we looked for a replacement class-D power amplifier to replace my old TDA2030 power amplifier build. While searching for a suitable power amplifier IC, we found TPA3001D1 from the local market. This IC is a slightly older 20W Class-D power amplifier manufactured by Texas Instruments. At the time of this writing, it is priced at LKR 180 (0.89 USD) in the local market and is still available at all major electronics stores (including online stores).
To minimize assembling difficulties, we used through-hole-type components in this PCB. The only SMD component in this PCB is the TPA3001D1 IC. We installed the power amplifier IC on the bottom of the PCB because then it would receive good airflow.
The dimension of the PCB is 45.71mm × 67.59mm and designed on a double-sided board. To build this PCB, we recommended the Seeed Fusion PCB fabrication service.
After assembly, we test this amplifier using a 12V power supply. As we have observed, this amplifier starts working from 7V without any distortion. We operated this amplifier at 75% volume continuously for one hour, where we did not notice any significant temperature change in the IC.
The Seeed Studio sponsor for this project. Seeed Fusion Service offers one-stop prototyping services for PCB manufacture, PCB assembly, and as a result, they produce superior quality PCBs and fast turnkey PCBA from 7 working days. Check out their website to know about their manufacturing capabilities and pricing.
The schematic and KiCAD PCB design files of this amplifier are available to download here.
I totally didn’t get bored and make a Class-D uniform for my Bitmoji what are you talking about. No I really didn’t what are you- HEY AMNESTICS!!! GET OVER HERE!

Diodes Incorporated announced a new family of high-voltage, high-speed gate drivers for converters, inverters, motor control, and Class-D power amplifier applications. These devices are suitable for motor drive applications up to 100V, and simultaneously can support power conversion and inversion applications operating at 200V. These features make the gate drivers well-suited for a number of …
Everything had been quiet, too quiet, all but the sound of their own footsteps on the metal floor. Clutching pages, keycards, and a few SCPs, the lonesome Class-D wandered down the dark corridors, hoping to find an exit. But down here, there seemed to be no checkpoints in sight, only finding an open containment chamber.
"I must've took a wrong turn." They muttered to themselves.
