7 W mono audio amplifier - kit

This is the Whadda WSAH4001 DIY Kit 7W Amplifier. This small amplifier is built around the IC TDA2003 that can deliver a maximum of 4Wrms into 4ohm. The IC is completely thermally and short-circuit protected. A normal DC voltage can be connected as a power supply.

With this kit you get a powerful amplifier at home. This small amplifier is specially designed around the IC TDA2003, which can deliver a maximum power of 4Wrms at 4 ohms. Thanks to the IC's thermal and short-circuit protection, your amplifier is protected against overheating and short-circuiting.

With a music power of 7W at 4 Ohm and an RMS output of 3.5W at 4 Ohm (or 2W at 8 Ohm), this amplifier delivers an impressive sound. The total harmonic distortion is only 0.05% at 1W and 1kHz, which ensures a clear sound reproduction.

The amplifier's frequency range extends from 20 Hz to 20 kHz (-3 dB), allowing you to enjoy a full spectrum of sound. With a signal-to-noise ratio of 86 dB (A-weighted) and an input sensitivity of 40 mV / 150 KOhm, this amplifier offers excellent sound quality.

The amplifier is also protected against overload and short circuit, so you don't have to worry about damage to your audio equipment. The amplifier can be powered with a normal DC voltage in the range of 8 to 18 VDC.

The manual of the Whadda WSAH4001 DIY Kit 7W Amplifier is available in different languages, including Dutch, English, French, German and Spanish. With its green color and compact dimensions of 55 mm wide, 35 mm deep and a weight of 42 g, this amplifier is easy to integrate into your audio projects. Get the most out of your audio experience with this Whadda Amplifier.
