20W Audio Amplifier Using TDA2020 Here is one another circuit in the series of audio power amplifier. We had already posted audio amplifier using transistor (3Watt, 10Watt and 20Watt) and using IC (7Watt and 20Watt). We used here IC TDA2020 for designing audio amplifier circuit. TDA2020 (IC1) can deliver a maximum of 20Watt into a 4Ω loads. Like the TBA810, the TDA2020 also incorporated thermal shutdown, and output short-circuit protection. The input impedance of the circuit 20Watt audio amplifier using TDA2020 is determined by resistor R1 and sensitivity is determined…

Here is another circuit in the series of audio power amplifiers. Previously we had already posted 3W and 20W audio amplifiers using transistors. Now we use an integrated circuit instead of transistors for designing audio amplifier circuits. By using IC TBA810 one can get a power output of 7W. The audio power amplifier featuring the TBA810 integrated circuit is shown in figure 1. This IC incorporated build-in-terminal shutdown, which automatically reduces the output in the event of sustained overloads or if the heat sinking arrangement is inadequate. We use a…
