Procurement Notes
Verify the specific suffix AV against official STMicroelectronics documentation to confirm exact pinout and thermal characteristics. Confirm RoHS compliance status as datasheet versions may vary. Ensure the Multiwatt-15 through-hole package matches your PCB design requirements before ordering.
Selection Notes
Select this component for high-power automotive audio designs requiring minimal external components. The internally fixed gain eliminates the need for bootstrap capacitors and Boucherot cells. Consider the diagnostic capabilities for production testing and the wide operating temperature range for harsh automotive environments.
Part Context
This part belongs to the TDA7375 family of Class-AB power amplifiers from STMicroelectronics. These devices are engineered specifically for the automotive infotainment sector, offering robust protection features and high efficiency in a compact surface-mount or through-hole form factor suitable for vehicle integration.
Replacement Considerations
Check for TDA7375 variants with different suffixes such as V or E if availability is an issue. Verify that any substitute maintains the same Multiwatt-15 footprint and electrical specifications for direct replacement.
