E-TDA7560

Overview

The E-TDA7560 is a Class AB audio power amplifier utilizing Multipower BCD technology in a Flexiwatt 25 package. It features a fully complementary P-Channel/N-Channel output structure for rail-to-rail voltage swing. Key electrical parameters include maximum output power of 4 x 80 W at 2 Ω, 4 x 51 W at 4 Ω, and 4 x 30 W at 4 Ω (14.4 V, 1 kHz, 10% THD). Supply voltage ranges from 8V to 18V with an internally fixed gain of 26 dB.

Feature Summary

• Multipower BCD technology with MOSFET output power stage
• Excellent low impedance driving capability
• Integrated standby and mute functions
• Comprehensive protection against short circuits and overtemperature

Applications

• High-power car radio systems
• Automotive infotainment amplifiers
• Vehicle cabin audio distribution

Procurement Notes

Verify the specific suffix or marking on the component body to confirm it matches the E-TDA7560 designation rather than the standard TDA7560. Confirm RoHS compliance status as the base model may have different environmental classifications. Check datasheet revisions to ensure feature parity regarding protection circuits and gain settings before finalizing procurement.

Selection Notes

Select this component when high output power into low impedances is required without external bootstrap capacitors. The internal fixed gain simplifies circuit design by eliminating external compensation networks. Ensure the application requires Class AB performance characteristics and can accommodate the thermal requirements of the Flexiwatt 25 package under maximum load conditions.

Part Context

This part belongs to STMicroelectronics' automotive audio amplifier portfolio, designed specifically for high-power applications in vehicle environments. It represents a specialized solution for car radios requiring superior distortion performance and robust drive capabilities compared to standard consumer audio ICs.

Replacement Considerations

The direct replacement listed is the E-TDA7560 itself, indicating it is the active version of the discontinued TDA7560. Verify pinout compatibility if substituting with other Quad Bridge amplifiers from the same family.
