TDA7360HS

Overview

The TDA7360HS is a Class AB audio power amplifier in the Multiwatt11H package designed for car radio applications. It delivers up to 22W bridge or 12W stereo output at 14.4V with 10% THD into 3.2Ω loads. The device features a fully complementary PNP/NPN output stage eliminating bootstrap capacitors, fixed voltage gain of 20dB (stereo) or 26dB (bridge), and an integrated clipping detector. Operating supply voltage ranges from 8V to 18V, with quiescent current of 120mA in stereo mode.

Feature Summary

• Integrated clipping detector circuit providing open-collector output for automatic volume control systems
• Delayed turn-on mute function eliminates audible on/off noise without external components
• Complementary PNP/NPN output configuration ensures high power performance without bootstrap capacitors
• Built-in protection against AC/DC short circuits, thermal overload, load dump voltage, and polarity inversion

Applications

• Car radio audio amplification
• Automotive speaker driving systems
• Bridge or stereo audio power stages

Procurement Notes

Verify the Multiwatt11H package variant matches the HS suffix requirement. Confirm automotive grade compliance if specified by system design. Check datasheet revision status as specifications are subject to change. Ensure thermal management aligns with the junction-to-case resistance limits provided in the official documentation.

Selection Notes

Select this component for applications requiring minimal external component count and robust protection features. The fixed gain simplifies circuit design compared to programmable amplifiers. Consider the thermal dissipation requirements given the Class AB topology and maximum power dissipation limits under varying ambient temperatures.

Part Context

The TDA7360 series represents STMicroelectronics' solution for cost-effective, high-power automotive audio. The HS suffix denotes the Multiwatt11H package with short leads, offering space-saving advantages over the standard V variant while maintaining identical electrical characteristics and pinout compatibility.

Replacement Considerations

TDA7360 is the direct equivalent part number. Verify package compatibility between Multiwatt11V and Multiwatt11H if substituting variants.
