Design of Dual to Mono Conversion Circuit for Class D Audio Amplifiers
A dual-channel-to-mono conversion circuit for class D audio power amplifiers is proposed,which can ef-fectively convert stereo amplifiers to mono amplifier.The circuit effectively reduces the output impedance of the power amplifier,reduces the dissipated power of the output power transistor,and improves the efficiency.At the same time,due to the principle of parallel operation,the total carrying current of mono mode increases,and the maximum output power of mono mode under the same total harmonic distortion is improved.
