What Is the TDA2030? 14W Audio Amplifier: Pinout and Uses
The TDA2030 is a medium-power (~14 W) audio power amplifier (TO-220, 5 leads). It builds a simple hi-fi amp with few parts; it runs from a single or dual (±) supply and needs a heatsink. It is far more powerful than the LM386. Pinout: 1 +IN, 2 −IN, 3 −Vs/GND, 4 OUTPUT, 5 +Vs.
The TDA2030 is a medium-power audio power amplifier (around 14 W). With a TO-220 body and few external parts, it is the classic way to build a simple but satisfying hi-fi amp. For the concept, see what is an audio amplifier.
What is the TDA2030 used for?
Desktop speakers, subwoofer driver stages and general-purpose audio amps. It runs from a single or dual (±) supply; it delivers far more power than the LM386. A heatsink is required.
TDA2030 pinout (TO-220 / Pentawatt-5)
| Pin | Function |

Specifications
| Parameter | Value |
|---|---|
| Power | ~14 W (depends on load/voltage) |
| Supply | ±6 – ±18 V (or single supply) |
| Body | TO-220 (5 leads) |
Watch out
A heatsink is a must. For stability and sound quality, apply the datasheet's feedback/Zobel components. For higher power, members like the TDA2050/TDA7297 or class-D (TPA3116) are preferred.
