![]() ![]() TDA7297 IC is a Stereo dual bridge, Class AB dual channel audio amplifier. The heart of this circuit is a TDA7297 amplifier IC. So, in Today’s tutorial, we will go through a step by step process on how to design a Stereo Audio Amplifier Circuit Using TDA7297 Dual Bridge Amplifier IC. ![]() Audio amplifiers have proven their worth in today’s electronics, whether it be a simple toy or a complex music production process.

You can also verify the results by putting resistors values in the formula given above. ![]() ![]() To achieve high ripple rejection ratios, bypass the ADJUST terminal. Therefore, in some applications, protection diodes are added which prevent the capacitors from discharging. The external capacitors can discharge due to the low current of the regulator. These capacitors help to remove ripples from output voltage.įor this reason, a heat sink is used to protect the IC from overheating. Download software east west quantum leap stormdrum kompakt edition However, we can also use capacitors to avoid voltage variations at the input and output terminals. To use it is a variable regulator, we have connected a potentiometer at the adjustable pin.īy changing the value of a potentiometer, you can obtain the desired voltage at the output. They are used to remove the undesired coupling and avoid the effect of noise.Ī capacitor of 1F is connected at the output to improve transient response. Its output can be adjusted by connecting a network of two resistors externally between the output pin and adjust the input pin. It has one drawback that during regulation its voltage drop to about 2.5V. It can be used as a fixed voltage regulator, AC voltage regulator, current limiter, Battery charger, local and on-card regulation.įurthermore, it can be used as a current regulator by connecting a resistor between the output and adjustment pin. ![]()
