FAQ:
Q: What is the input voltage required to drive the amplifier fully?
A: The input must be about 100-500 mV to drive amplifier fully. Previously, you may like LM386 amplifier circuit. But you may also like this circuit as well. This type of circuit using few components needs no transformers and provides very good results.
Q: What is a 250 mw amplifier?
A: Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design. This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased. This gives us a 250 mW amplifier, enough to drive a loudspeaker to the same volume as a mobile phone or MP3 player.
Q: What is a 4 transistor audio amplifier circuit?
A: This is a 4 transistor audio amplifier circuit. Which is a 4-transistors complementary push-pull amplifier, that shows the basics of audio amplifier design. This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased.
Q: How to connect Q1 and Q2 to a common-emitter amplifier?
A: First see INPUT stage, Q1 acts as a voltage amplifier in direct coupling mode. Second, DRIVER stage, Q2 is connected with the common-emitter, and directly connect with Complementary common-collector amplifier by Q3 and Q4.
