TDA7569LV

Overview

The TDA7569LV is a four-channel Class-AB differential power amplifier designed for automotive audio applications. It operates within a supply voltage range of 6 V to 18 V and supports load impedances of 2 Ohms and 4 Ohms. The device delivers an output power of 50 W with a total harmonic distortion plus noise (THD+N) of 0.3%. It features a PowerSO-36 surface-mount package, AEC-Q100 qualification, and an operating temperature range from -40°C to +85°C.

Feature Summary

Four-channel differential input architecture providing improved disturbance rejection
Integrated full I2C bus diagnostics for speaker status monitoring
High efficiency Class-SB operation mode for reduced power dissipation
Robust protection against misconnections and battery transients

Applications

Automotive car radio amplifiers
Digital instrument clusters with integrated audio
Start-stop compatible vehicle audio systems

Procurement Notes

Verify the specific suffix (e.g., BLV, LVPD) as it determines the package type and thermal characteristics. Confirm current production status, as variants may be marked as Not Recommended for New Designs. Ensure compatibility with the target PCB footprint for the selected PowerSO or DIL package version before ordering.

Selection Notes

Select this component for designs requiring high channel count in a single IC with comprehensive digital diagnostics. The differential input stage is suitable for noisy automotive environments. Verify that the system can support the required 2 Ohm or 4 Ohm load configurations to achieve the specified power output levels under the intended supply voltage conditions.

Part Context

This part belongs to STMicroelectronics' family of advanced BCD technology quad bridge car radio amplifiers. It shares functional similarities with the TDA7569BLV and TDA7569BDLVPD but differs in packaging and specific thermal ratings. The series emphasizes low voltage operation and high efficiency for modern automotive emission standards.

Replacement Considerations

TDA7569BLV: Similar functionality but typically in a through-hole DIL package. TDA7569BDLVPD: Surface mount variant with potentially different thermal performance. Verify pinout compatibility and package dimensions when substituting.
