Low Voltage Audio Amplifier. Jim Keith. This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to consider and much to learn. To the best of my knowledge the following information is new to the world.

Each of the 12 transistors do not have to slew up the output as much when compared to the 4 transistor amp). As long as the power supply is capable, the 12-transistors will be more efficient in having more current on tap for the demanding music passages (even at …

If you are looking for ultra low voltage noise (2 ohm base resistance), BFG16A (SOT223A) or BFQ17 (SOT89) might be interesting. Mind you, hFE is not very high and as far as I remember the 1/f corner is not particularly low, so these are not the right transistors if you want low current noise. See www.semiconductors.philips.com for more info.

Best transistor to use for audio amplifier - Electrical ...

Input transistors should be low noise. BJT tend to be lower noise if the correct source impedance (for op amps you can look this up in the datasheet by looking at voltage noise / current noise which for NE5534A at 30Hz is ~5.5/0.0015 = 3k7). JFET has super low current noise so they will tend to have better noise performance with high Z inputs.

Low Cost Amplifier Circuit Using Three Transistors

Low Cost Amplifier Circuit Using Three Transistors In Audio Circuits Low cost amplifer. Description. No big deal here! You can make a decent power amplifier using just three transistors. All components used here can be obtained from your electronic junk box. Also you just need a 9V transistor radio battery to power this circuit.
