Medium Power Audio Amplifier
Using IC TDA1010/TDA1011
In our day-to-day life we always hear our radio set, if you are having a small transistor or a Walkman and if you want to hear it aloud, you need a good amplifier, but a good amplifier is very costly. The circuit diagram that I have shown below employs an IC TDA1010 that delivers upto 10W of power into a 4 ohms speaker load.
The power range of the IC TDA1010 is from 1W to 10W, of course when you use it to deliver 1W of power with 6V DC and there is no need of heat sink. For application that requires upto 10W of power output need a power supply of 12v with a HEAT SINK. The power output can be controlled by the potentiometer of 1M-log type, which in turn control the volume of the system.The IC TDA1010 can be replaced DIRECTLY by the IC TDA1011.
The power supply suggested is a simple bridge rectifier with capacitor as a ripple filter whose output is further regulated by IC LM7812 .The LM7812 requires a HEAT SINK when used with such a amplifier, no need for a T0-2 type of IC packet for this application.
