Overview
The TDA7296 is a monolithic Class-AB audio power amplifier utilizing Multipower BCD technology and a DMOS output stage. It operates within a wide supply voltage range of ±10V to ±35V (70V total) and delivers up to 60W of music power into 8Ω loads. Key electrical parameters include an 80dB gain, 5A maximum output current, and 10mV input offset voltage. The device features built-in mute and standby functions with turn-on delay, short-circuit protection, and thermal shutdown. It is housed in a Multiwatt-15 through-hole package.
Feature Summary
- Integrated muting and standby functions eliminate switching noises during power transitions.
- DMOS power stage enables high output power capability even with poor supply regulation.
- Built-in protections include short-circuit prevention and thermal shutdown for reliability.
Applications
- Hi-Fi home stereo systems
- Self-powered loudspeakers
- Top-class television sets
Procurement Notes
Verify the specific suffix variant (e.g., AV, HS, S) against the design requirements, as these may indicate differences in packaging or minor electrical tolerances despite shared core functionality. Confirm the Multiwatt-15 package availability matches the PCB footprint. Ensure the selected component meets the required operating temperature range of 0°C to +70°C for the intended application environment.
Selection Notes
Select this component for applications requiring high voltage tolerance and robust power delivery in a single-channel configuration. The wide supply range allows flexibility in power supply design. Consider the thermal management requirements due to the 50W dissipation capability. The differential input type simplifies circuit interfacing compared to single-ended alternatives.
Part Context
The TDA7296 belongs to STMicroelectronics' series of DMOS audio amplifiers, sharing pin compatibility with models like the TDA7293, TDA7294, and TDA7295. It is designed for high-fidelity audio reproduction, offering low distortion and noise characteristics suitable for premium consumer electronics. The device represents a mature solution for analog audio amplification needs.
Replacement Considerations
TDA7296A, TDA7296AV, TDA7296HS, TDA7296S, and TDA7296SV are documented variants with identical functional descriptions regarding the 70V/60W DMOS amplifier capabilities. Verify package and suffix specifications when substituting.
