An impressive 120 watt amplifier circuit can be built by cascading a couple of TDA 2030 IC in a bridged tied load (BTL) configuration and through a few current boosting transistors. Advantage of a BTL Amplifier Topology The main objective of a BTL configuration is to enable a two way operation of the load which […]
