Where to use TDA2822 Amplifier IC

The TDA2822 is a Dual Audio Amplifier IC, meaning it has two Op-Amps inside its package, and they are commonly used for audio amplification because of their wide bandwidth gain. The two outputs can deliver 250 milliwatts of output power. This IC can be used in portable audio systems, preamplifiers, hearing aid mini radios, headphone amplifiers, etc.

So if you are looking for a dual package Operational amplifier IC with high gain, and wide bandwidth for audio amplification, then this IC might be the right choice for you.


How to use TDA2822 Amplifier

An application circuit from the TDA2822 datasheet is given below

How to use TDA2822 Amplifier.png

The left load is connected to output pin 1 of the IC through electrolytic capacitor C4, and the right load is connected to output pin 3 through electrolytic capacitor C5. The Inverting Input Pins (5 and 8) are connected to the ground via electrolytic capacitors. Non-Inverting Input Pins (7 and 6) are connected to input1 and input2. Pin 2 is connected to the DC supply and pin 4 is connected to the ground. Electrolytic capacitor C3 is connected across VCC and groundworks as a filter capacitor.
