HiFi or High fidelity term is used to indicate equipment, which gives a sound of high quality. Their best feature is their inaudible noise or distortions and natural frequency response. These amplifiers are known to create sounds with utmost clarity so it is a dream of all music lovers to get their hands on one. Here we are going to discuss the circuit of the Hi-Fi amplifier by using TDA2616.

Hi-Fi Amplifier Circuit
Working & Description:
- Circuit delivers 12 Watts power on 8 Ohm speaker for each channel at +/- 12 V dual supply.
- K1 & K2 are speakers on pins 4 & 6
- 3 and 8 are grounded
- 1 and 9 are left and right inputs
- 5 and 7 are provided voltages
- Circuits consist of capacitors and resistors combination.
Tips for better results:
- Use ceramic capacitors.
- Capacitors must be rated 50V.
- Use a well-regulated and filtered +/- 12 V dual power supply that is able to provide at least 2 A continuous current.
- Use PCB of good quality
