TDA7391LVPDTR

Overview

The TDA7391LVPDTR is a single-channel Class-AB audio power amplifier designed for automotive applications. It operates within a supply voltage range of 6V to 18V and delivers up to 45W into a 3.2-ohm load. The device features differential inputs, short-circuit protection, thermal shutdown, and standby functionality. Packaged in a 20-PowerSOIC surface-mount format, it supports low-voltage 'start-stop' profiles and e-call compatibility.

Feature Summary

Supports both differential and single-ended input signal configurations
Includes internal clipping detector for gain compression implementation
Features comprehensive protection against short circuits, overtemperature, and load dump

Applications

High-power car radio amplifiers
Automotive audio systems requiring low voltage operation
Start-stop compatible vehicle audio equipment

Procurement Notes

Verify the specific suffix PDTR indicates tape-and-reel packaging versus tube variants like PDU. Confirm AEC-Q100 qualification status for your specific automotive grade requirements. Check current RoHS3 compliance documentation before final integration. Ensure the PowerSO-20 footprint matches your PCB layout constraints.

Selection Notes

Select this component when high output power is required with minimal external components due to fixed internal gain. It is suitable for designs needing compatibility with fluctuating automotive battery voltages during engine stop. Consider the thermal performance of the PowerSO package for your enclosure design.

Part Context

This part belongs to the TDA7391LV series, which includes bridge class AB amplifiers optimized for car radios. The LV designation signifies low voltage operation capabilities. Related parts include the TDA7391PD and TDA7391PDU, which share similar electrical characteristics but differ in packaging and reel specifications.

Replacement Considerations

Direct substitutes include TDA7391PD and TDA7391PDU. Verify that the alternative package type (tube vs. reel) meets your assembly line requirements. Electrical parameters remain consistent across these variants within the same series.
