TDA7501

Overview

The TDA7501 is a specialized automotive audio signal processor manufactured by STMicroelectronics. Designed for digital car radio applications, it integrates AM and FM specification support within a single integrated circuit. The device operates on a supply voltage ranging from 7.5V to 10V and functions reliably across an ambient temperature range of -40°C to +85°C. It features six audio channels and communicates via I2C and SPI interfaces. Packaged in a 44-LQFP (10x10 mm) surface-mount format, the component meets automotive grade standards for reliability in vehicle environments.

Feature Summary

• Six-channel audio signal processing capability
• Supports AM and FM radio specifications
• Dual interface compatibility with I2C and SPI protocols
• Automotive grade qualification for vehicle durability

Applications

• Digital car radio systems
• Automotive audio signal processing units
• Vehicle infotainment front-end modules

Procurement Notes

Verify the specific package variant upon ordering, as local data indicates a Tray packaging option while other sources reference Tape & Reel configurations. Confirm that the 44-LQFP (10x10) footprint matches the target PCB design. Ensure the supplier provides documentation confirming the automotive grade status and the 7.5V to 10V operating voltage range for system integration.

Selection Notes

Select this component when designing automotive radios requiring integrated AM/FM processing with six output channels. The 44-LQFP package suits designs needing a compact 10x10 mm footprint with surface-mount assembly. Verify that the host controller supports both I2C and SPI communication protocols required for configuration and control of the signal processor parameters.

Part Context

The TDA7501 belongs to STMicroelectronics' portfolio of specialized audio integrated circuits tailored for the automotive sector. It serves as a dedicated solution for digital signal processing in car radios, distinct from general-purpose consumer audio chips. Its design focuses on meeting the rigorous environmental and electrical demands of modern vehicle infotainment systems.
