TDA7240AV

Overview

The TDA7240AV is a discontinued Class AB bridge audio amplifier IC manufactured by STMicroelectronics, designed for car radio applications. It operates within an 8V to 18V supply voltage range and delivers up to 20W output power into a 4Ω load at 1kHz with 10% distortion. The device features a compact Heptawatt-7 vertical package with bent and staggered leads, supporting junction temperatures from -40°C to 150°C.

Feature Summary

• Integrated protection against AC/DC short circuits to ground and across the load
• Built-in thermal shutdown and loudspeaker protection mechanisms
• Stand-by functionality with low current consumption
• High current capability with minimal external component requirements

Applications

• Car radio bridge amplifiers
• Automotive audio systems requiring compact power solutions

Procurement Notes

Verify component obsolescence status before procurement planning as this part is marked obsolete. Confirm availability through authorized distributors or secondary markets. Ensure design compatibility with the Heptawatt-7 vertical package dimensions and pinout configuration during integration.

Selection Notes

Select this component for automotive designs requiring a single-channel bridge amplifier in a space-constrained environment. Evaluate thermal management requirements given the 16W dissipation rating at 85°C case temperature. Consider the 18V maximum operating supply voltage when designing power rails.

Part Context

This model belongs to the TDA7240 family of bridge audio amplifiers. The 'V' suffix denotes the specific Heptawatt-7 vertical package variant with bent and staggered leads, distinct from the horizontal 'H' package version. Both variants share identical electrical characteristics and protection features.

Replacement Considerations

No officially confirmed substitute part numbers are documented in the provided datasheet.
