YINETTECH TDA2030A – audio power amplifier ICs, 10 pieces

The TDA2030A is a popular monolithic integrated circuit that serves as the power stage in audio amplifiers. The set contains ten pieces in a 5-pin package, which is enough for several stereo projects, repairing older equipment, or a spare stock on the workshop shelf.

What it is for

The chip amplifies the signal from a preamplifier enough to drive a speaker. It works well in DIY home amplifiers, active speakers, radios and simple Hi-Fi sets. According to the seller's description, it delivers about 18 W of power with a symmetrical ±16 V supply into a 4 ohm load, at distortion of around 0.5 percent.

Protection and power

• output short-circuit protection,
• thermal protection of the chip,
• protection against accidental ground disconnection,
• works with both single and dual supply.

The chip requires a heat sink, because it gives off a lot of heat during longer operation. The supply voltage range given in the specification is 6 to 22 V.

Key data

It is a cheap and proven way to build or repair an audio amplifier yourself. Before buying it is worth checking the datasheet and choosing a suitable power supply and heat sink.

As an audio power amplifier IC, the TDA2030A serves as the power stage in the signal chain, and a well-designed Hi-Fi amplifier with this chip sounds clean and clear.
