STMicroelectronics TDA7451 is a Class AB audio amplifier IC designed for high-fidelity audio applications. This component offers flexible output configurations, supporting either dual-channel (stereo) or quad-channel (4-channel) operation. It features integrated protection mechanisms including depop, mute, short-circuit, and thermal shutdown, ensuring robust performance. The TDA7451 is housed in a 25-Flexiwatt (vertical) package with formed leads, suitable for through-hole mounting. Key performance specifications include a maximum output power of 32W per channel into a 4-ohm load for stereo configuration, and 9.5W per channel into a 4-ohm load for quad-channel configuration. The operating temperature range is -40°C to 150°C (TJ). This amplifier is utilized in automotive audio systems and home entertainment equipment.
