TDA7718NTR

Overview

The TDA7718NTR is a three-channel audio signal processor designed for automotive applications. Manufactured by STMicroelectronics, it operates within a supply voltage range of 7.5V to 10V and supports an ambient temperature range of -40°C to +85°C. The device features an I2C interface for control and is housed in a 28-TSSOP package with a width of 4.40mm. It holds AEC-Q100 qualification, ensuring reliability for automotive environments. The component is supplied in tape and reel or cut tape formats.

Feature Summary

• Three-channel audio signal processing capability
• I2C digital interface for configuration and control
• AEC-Q100 qualified for automotive grade reliability
• Operates on 7.5V to 10V supply voltage

Applications

• Automotive audio systems
• Car audio processors
• Vehicle sound management units

Procurement Notes

Verify the specific ordering suffix 'NTR' corresponds to the Tape & Reel packaging format as indicated by local source data. Confirm current availability status, as related variants in this series may have discontinuation notices. Ensure design compatibility with 28-TSSOP footprint and I2C bus requirements before procurement.

Selection Notes

Select this component when a dedicated three-channel audio processor with automotive certification is required. The I2C interface necessitates a compatible microcontroller or host controller. Verify that the system power supply remains stable between 7.5V and 10V. Consider the 28-TSSOP package dimensions for PCB layout constraints.

Part Context

This part belongs to the TDA7718 family of audio signal processors from STMicroelectronics. Variants such as TDA7718B and TDA7718N share similar core functionalities but differ in packaging options like tubes versus reels. The NTR suffix specifically denotes the reel-based packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include other TDA7718 family members like TDA7718N or TDA7718B, provided the packaging difference (tube vs. reel) is acceptable for the manufacturing process. Verify pinout and electrical specifications match exactly before substitution.
