TDA7786

RF Receivers Overview

The TDA7786 is an AEC-Q100 qualified AM/FM/WB tuner IC for automotive applications. It operates on a single 5V supply with 175mA receive current. The device features a fully integrated VCO, PLL synthesizer, and IF amplifiers. It supports I2C control and I2S digital audio interfaces. The component is housed in a 64-LQFP (10x10) package and functions within a temperature range of -40°C to 85°C.

RF Receivers Feature Summary

• Integrates mixers, IF amplifiers, stereo decoder, and RDS demodulator on a single chip.
• Utilizes digital signal processing for high selectivity and adaptive bandwidth control.
• Supports HD Radio reception via digital interface when combined with external baseband decoder.
• Includes automatic self-alignment for FM front-end pre-selection filter and image rejection.

RF Receivers Applications

• AM/FM car-radio tuners
• Weather band reception systems
• HD Radio compatible automotive audio units

RF Receivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact hardware revision and packaging configuration. Note that this product has been officially discontinued as of August 5, 2025. Ensure compatibility with existing system designs before procurement attempts, as availability is limited to remaining stock or secondary markets.

RF Receivers Selection Notes

Select the TDA7786 for entry-level high-performance automotive tuning requirements. Choose the TDA7786M variant if enhanced performance in FM multipath conditions is required due to its proprietary MuSICA algorithm. Both versions maintain hardware and software compatibility within the ELITE tuner family.

RF Receivers Part Context

The TDA7786 belongs to the STMicroelectronics ELITE tuner family, optimized for car-radio applications. It leverages digital signal processing to minimize external components and space occupation. The device integrates essential radio functions including VCO, PLL, and IF processing, providing a compact solution for modern automotive audio systems.

RF Receivers Replacement Considerations

The TDA7786M serves as a functional alternative within the same family, offering improved FM multipath handling via the MuSICA algorithm while maintaining full hardware and software compatibility with the standard TDA7786 model.

RF Receivers FAQ

Does the TDA7786 support HD Radio reception?

Yes, it includes a digital interface for HD Radio reception when used in combination with an external baseband decoder.

What is the difference between TDA7786 and TDA7786M?

The TDA7786M includes the proprietary MuSICA algorithm for enhanced behavior in FM multipath conditions, whereas the TDA7786 is the standard entry-level version.
