Overview
The TDA7240AH is a 20W bridge audio amplifier IC designed for car radio applications. It operates on an 18V supply voltage and delivers up to 20W output power into a 4-ohm load at 1kHz with 10% distortion. The device features a compact Heptawatt H package, low external component count, and comprehensive protection including short circuits, thermal shutdown, and load dump transients.
Feature Summary
- Integrated protection against AC/DC output short circuits to ground and across the load
- Built-in thermal shutdown and loudspeaker protection mechanisms
- High current capability with low distortion and noise characteristics
- Designed for minimal external component requirements in automotive environments
Applications
- Car radio audio amplification
- Automotive sound systems
- Bridge-mode audio signal processing
Procurement Notes
Verify component authenticity through authorized STMicroelectronics distributors. Confirm package variant matches Heptawatt H specifications. Check datasheet revisions for updated electrical parameters. Ensure storage conditions comply with specified temperature ranges. Validate pinout alignment before PCB integration.
Selection Notes
Select this component for high-power automotive audio applications requiring robust protection features. Consider the Heptawatt H package dimensions for thermal management and board space constraints. Evaluate supply voltage stability requirements given the 18V maximum rating. Assess heat dissipation needs based on expected output power levels.
Part Context
Part of the TDA7240A family featuring different package variants. The Heptawatt H variant offers specific mechanical dimensions compared to other versions. Designed specifically for automotive electronics with emphasis on reliability under harsh operating conditions.
Replacement Considerations
TDA7240AV serves as a direct replacement with identical electrical characteristics but utilizes the Heptawatt V package. Verify mechanical compatibility when substituting between H and V package variants.
