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. Here are some benefits of BTL configuration: No need large capacitor for DC blocking (decoupling) […]
