Working Principle of TDA7264

The TDA7264 works on a Class-AB amplifier architecture, providing a balance between sound quality and power efficiency. Audio signals fed into the input pins pass through internal biasing and low-noise preamplification circuits.

The bootstrap circuitry enhances output swing, allowing the IC to deliver stronger audio signals without distortion. Both stereo channels amplify the input signals independently, resulting in clean and powerful audio output for 8Ω speakers.

Built-in thermal shutdown and short-circuit protection constantly monitor the device’s operating conditions, preventing damage during abnormal loads or overheating.
