TDA7360

Overview

The TDA7360 is a Class AB audio power amplifier in the Multiwatt package designed for car radio applications. It delivers up to 22W bridge or 12W stereo output at 10% THD with a 4Ω load and 14.4V supply. Operating voltage ranges from 8V to 18V, with peak capabilities of 50V. Key features include no bootstrap capacitors, fixed gain (20dB stereo), and an open-collector clipping detector. Protections cover AC/DC shorts, thermal overload, load dump, and ESD.

Feature Summary

• Fully complementary PNP/NPN output configuration enables high power performance without bootstrap capacitors.
• Integrated delayed turn-on mute circuit eliminates audible on/off noise during power transitions.
• Open-collector clipping detector output drives automatic volume control systems when distortion thresholds are reached.
• Comprehensive protection array includes short circuit, thermal shutdown, load dump, and loudspeaker DC current safeguards.

Applications

• Car radio main amplifiers
• Automotive active speaker systems
• Bridge-mode automotive audio setups

Procurement Notes

Verify the specific ordering suffix against the datasheet to confirm package variant. The standard part uses Multiwatt11V, while the HS suffix indicates Multiwatt11H. Ensure the component matches the required pinout and thermal characteristics for your design. Confirm availability status as this is an older generation product.

Selection Notes

Select this amplifier for cost-sensitive automotive designs requiring minimal external components. It supports both stereo and bridge configurations without additional parts. The low standby current allows for simple power switching. Verify that the 20dB fixed gain meets your pre-amplifier requirements.

Part Context

This device belongs to STMicroelectronics' legacy line of Class AB automotive audio amplifiers. It utilizes Multiwatt packaging for efficient heat dissipation in compact car radio enclosures. The technology focuses on reducing bill-of-materials costs by eliminating bootstrap and Boucherot cells while maintaining robust protection features.

Replacement Considerations

TDA7360HS serves as the direct package variant replacement using the Multiwatt11H housing. Other family members like the TDA7376B offer similar functionality with updated diagnostic features but require different pin mapping.
