| Abstract: | As the post amplifier circuit of electronic equipment, the low - frequency power amplifier~ main role is to amplify the power of pre - level audio signal to drive the work load, and to get a good sound effect. This paper designs a low - frequency power am- plifier used in the underwater acoustic signal generating system, the circuit takes the preamplifier chip NF_5532, the power amplifier chip TDA2030 and the DC regulated power supply as core to realize the power amplification for small signal. After the simulation with Multisim, this circuit works stably; the output waveform has no distortion and can meet the design requirement in output power and am- plifier gain. |
