TDA7499

Overview

The TDA7499 is a Class AB dual-channel audio power amplifier designed for high-fidelity sound applications. It delivers 6W+6W into an 8Ω load at ±14V supply, with a maximum output of 10W per channel under specific conditions. The device operates within a wide supply voltage range of ±5V to ±18V (10V to 36V single). Key electrical parameters include a total harmonic distortion plus noise of 0.2%. It features mute and standby functions, pop-free turn-on/off capabilities, and is housed in a Multiwatt11V package.

Feature Summary

• Integrated mute and standby control functions for flexible system management
• Pop-free operation during power-up and power-down sequences
• Wide supply voltage compatibility supporting various automotive and consumer power rails

Applications

• High-fidelity music systems
• Automotive audio amplifiers
• Consumer home theater setups

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure correct pinout and thermal specifications. Confirm availability status as components may be subject to discontinuation or limited stock. Cross-reference the package type Multiwatt11V with your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a stereo Class AB amplifier with integrated mute and standby controls is required. Ensure the design supports the ±5V to ±18V supply range. Verify that the thermal dissipation requirements for the Multiwatt11V package are met by the enclosure design. Check if the 6W+6W output rating meets the speaker impedance and voltage constraints of the target application.

Part Context

This part belongs to STMicroelectronics' audio power amplifier family, specifically tailored for stereo applications requiring moderate power output. It complements other TDA series amplifiers by offering integrated control features like mute and standby, reducing external component count compared to basic amplifier ICs lacking these functions.

Replacement Considerations

Check for direct pin-to-pin replacements within the TDA74xx series. Verify if upgraded variants offer higher efficiency or different packaging while maintaining the same functional interface and electrical characteristics for seamless integration.
