Compact 3W BTL Audio Power Amplifier TDA7056

Schematic Diagrams      Comments Off on Compact 3W BTL Audio Power Amplifier TDA7056

Bridge-tied-load (BTL) configuration in an amplifier is basically a H-network  with the loud-speaker as the “bridge” between two active valve or switcher. This configuration allow a full alternating current signal to be produced at the load (loudspeaker) without a transformer or a symmetric power supply.  Using integrated circuit, such BTL… Read more »

200W Mono / Stereo Power Amplifier using TDA1514A

This is circuit design of 200W mono / stereo power amplifier using TDA1514A. This circuit support mono and stereo channel. Mono channel uses bridge configuration, so the mono choice will be give power output by twice than stereo choice. A symetrical power supply (dual polarity) is required to powered this… Read more »
