TDA2003 2.0 Dual Channel Stereo Power Amplifier Board with Switch Small and Medium Power Amplifier

TDA2003 2.0 Dual Channel Stereo Power Amplifier Board with Switch Small and Medium Power Amplifier
Description:
This circuit uses TDA2003 domestic integrated block, the circuit is simple, the passband is wide, the sound quality is beautiful, exclusive optimization, ultra-quiet, no impact, and can be widely used in various audio and small and medium power audio equipment, audio amplifier circuits, etc.
It has the characteristics of small size, high output power, low distortion, etc. The chip has its own internal protection circuit, few external components, high output power, and adopts a small package (TO-220), which can increase the assembly density, and the switch machine has no impact and will not It damages the horn and contains various protection circuits, so it works stably and reliably.
The power amplifier module has low power consumption and large enough output sound. It uses ordinary full-range speakers and has a 3P fan interface. You can directly use computer fans and support fan cascade. Use it to DIY refit as the power amplifier part of home active speakers or A small power amplifier couldn’t be more suitable.
