TDA7480L

Overview

The TDA7480L is a single-channel mono Class-D audio power amplifier manufactured by STMicroelectronics. It operates on a dual supply voltage ranging from ±10V to ±16V and delivers up to 10W of output power into an 8-ohm load. The device is housed in a 20-pin DIP package with a pitch of 0.300 inches (7.62mm). Key integrated features include mute, short-circuit protection, thermal overload protection, and standby functionality.

Feature Summary

• Class-D topology for high efficiency
• Integrated mute and standby modes
• Short-circuit and thermal protection

Applications

• Automotive audio systems
• Car radio amplifiers
• Active speaker applications

Procurement Notes

Verify component status as the TDA7480L is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing 20-DIP footprints during replacement planning. Check RoHS compliance status against current regulatory requirements before integration.

Selection Notes

Select this component for designs requiring a single-channel mono Class-D amplifier with DIP packaging. Suitable for applications needing integrated protection features like mute and thermal shutdown. Consider the ±10V to ±16V supply range when designing power stages. Evaluate alternatives if surface-mount packages are preferred.

Part Context

Part of the TDA7480 family of automotive audio amplifiers. Designed for robust performance in vehicle environments. Shares functional similarities with other STMicroelectronics Class-D amplifiers but differs in channel count and package type.

Replacement Considerations

Check for direct pin-compatible substitutes within the TDA748x series. Verify electrical parameters match original design requirements. Consider newer generation amplifiers if obsolescence impacts long-term supply.
