Analog signal power amplifier circuit |
摘要 |
A signal corresponding to an analog input signal is supplied to one of two input terminals of a two-input, one-output MOS differential amplifier. A reference voltage signal is supplied to the other of the two input terminals of the MOS differential amplifier. A bipolar transistor having one end connected to an analog signal output terminal is driven by a signal from the output terminal of the MOS differential amplifier. A loudspeaker is driven by the bipolar transistor.
