There are many ready-made chip amp audio ICs. Designing such low voltage yet very powerful amplifier using discrete components can be very difficult and time consuming. So better can be to buy such commercially available cheap ICs. You can try TDA2822. It can run as low as 3V, class AB type, but this chip is becoming obsolete today.

In the first part of lab#1 you will construct a low-power audio amplifier/speaker driver based on the LM386 IC from National Semiconductor. The audio amplifier will be a self-contained, battery-operated component. In the second part of the lab you will construct a microphone circuit using a compact electret condenser microphone cartridge.

O(RMS) = 2 x 4, which means that the RMS output voltage from the audio power amplifier must be 2.83 V. Because the peak-to-peak output voltage of the CODEC is 3 V, convert this to RMS voltage,

mono from any low impedance audio source such as a compact disc or MP3 player. The input must not exceed the maximum voltage level of 250mV peak, since audio quality can not be guaranteed at such levels. The system must drive two 8-Ohm speakers with a minimum gain of –3dB and 20dB. This is 0.7V/V and 10V/V in terms of amplitude.
