What Is BTL Power Amplifier?

- Jun 20, 2018-

BTL power amplifier also known as bridge push-pull circuit, power amplifier output stage and the speaker using a bridge-type contact between the main solution to OCL, OTL power amplifier efficiency is high, but the power utilization is not high. Compared with OCL and OTL power amplifiers, BTL is 3 to 4 times higher than their output power at the same operating voltage and the same load conditions. In the case of a single power supply, BTL cannot use output capacitors, and the power supply utilization is general. Twice the single-ended push-pull circuit, suitable for applications where the supply voltage is low and greater output power is required.
