Description
The TDA7266SA is a dual bridge amplifier specially designed for LCD Monitor, PC Motherboard, TV and
Portable Radio applications.
A dual bridge amplifier, also known as a full bridge amplifier or an H-bridge amplifier, is an electronic circuit that is commonly used to drive loads such as motors, speakers, or other devices that require bidirectional control. It consists of four switching elements (typically transistors) arranged in a bridge configuration.
Pin to pin compatible with: TDA7266S, TDA7266, TDA7266M, TDA7266MA, TDA7266B, TDA7297SA
& TDA7297.

Block Diagram
The operation of a dual bridge amplifier involves switching the transistors in pairs. When one pair of transistors is turned on, it allows current to flow in one direction through the load. When the other pair of transistors is turned on, it allows current to flow in the opposite direction. By controlling the switching timing and duty cycle, the average voltage and current across the load can be adjusted, enabling precise control over its movement or output.
Dual bridge amplifiers find applications in various fields, including robotics, motor control, audio amplification, and power electronics.
