TDA7708L52

RF Receivers Overview

The TDA7708L52 is an automotive-grade RF receiver designed for infotainment systems, supporting AM, FM, RDS, and SW-LW bands with a maximum frequency of 108MHz. It operates on a supply voltage range of 3.15V to 3.45V and draws a receive current of 350mA. The component features I2C, I2S, and SPI data interfaces and is housed in a 64-VFQFPN (9x9mm) surface-mount package. It functions within a temperature range of -40°C to +85°C and holds AEC-Q100 qualification.

RF Receivers Feature Summary

• Supports multiple radio modulation protocols including AM, FM, RDS, and Shortwave/Low Frequency bands.
• Integrated digital interfaces for system control and audio data transmission.
• Qualified for harsh automotive environments with extended temperature tolerance.

RF Receivers Applications

• Automotive AM/FM radio receivers
• Vehicle infotainment systems
• RDS signal processing modules

RF Receivers Procurement Notes

Verify the specific suffix L52 against official STMicroelectronics documentation to confirm the tray packaging configuration, as other variants like SCBTR use tape and reel. Ensure the procurement channel provides valid traceability for AEC-Q100 certified components intended for automotive safety applications. Cross-reference the exact part number with the manufacturer's active product list to avoid obsolete stock.

RF Receivers Selection Notes

Select this component when designing systems requiring integrated support for LW/SW bands alongside standard FM/AM reception. The 64-pin VFQFPN package offers a compact footprint suitable for space-constrained automotive PCB layouts. Consider the 350mA current consumption during power budget calculations for battery-operated or low-power vehicle architectures.

RF Receivers Part Context

This part belongs to the TDA7708 family of high-performance audio ICs from STMicroelectronics. It serves as a specialized RF front-end solution for modern vehicle entertainment systems, replacing discrete tuner designs with a single-chip integration approach that simplifies board layout and reduces component count.

RF Receivers Replacement Considerations

The TDA7708SCBTR is a documented alternative within the same family, though it utilizes a 52-VFQFPN (8x8mm) package and tape-and-reel shipping instead of the L52's 64-pin tray format. Verify pin compatibility and software configuration before substitution.
