TDA7498ETR

Overview

The TDA7498ETR is a dual BTL Class-D audio amplifier manufactured by STMicroelectronics, designed for home systems and active speaker applications. It operates on a wide-range single supply voltage of 14 V to 36 V. The device delivers 160 W per channel at THD = 10% with a 4 Ω load and 36 V supply, or 220 W in mono parallel BTL mode with a 3 Ω load. It features four selectable fixed gain settings (nominally 23.8 dB, 29.8 dB, 33.3 dB, and 35.8 dB), differential inputs, standby/mute control, and smart protection including thermal overload and overcurrent shutdown. The component is housed in a 36-pin PowerSSO package with an exposed pad up (EPU) and supplied in tape and reel packaging.

Feature Summary

• Dual BTL Class-D architecture supporting stereo or mono parallel BTL configurations via the MODE pin
• High efficiency operation with integrated smart protection against thermal overload and overcurrent conditions
• Differential input design to minimize common-mode noise and improve signal integrity
• Exposed pad up (EPU) package facilitating direct mounting of external heatsinks

Applications

• Home audio systems
• Active speaker applications
• Mono parallel BTL audio setups

Procurement Notes

Verify the specific ordering code TDA7498ETR corresponds to the required PowerSSO-36 EPU package and tape and reel packing configuration. Confirm that the operating temperature range of 0 °C to 70 °C aligns with your system requirements. Ensure compatibility with the specified single-supply voltage range of 14 V to 36 V during integration.

Selection Notes

Select this component when high output power is required from a single-supply Class-D amplifier. The availability of multiple fixed gain settings allows flexibility in system design without external resistors. The exposed pad up package is suitable for designs requiring efficient heat dissipation through an external heatsink rather than relying solely on PCB copper area.

Part Context

The TDA7498ETR belongs to the TDA7498 family of dual BTL Class-D audio amplifiers. It shares core specifications with the TDA7498E but differs in packaging format, utilizing tape and reel delivery instead of tube packaging. This variant is intended for automated surface-mount assembly processes in high-volume manufacturing environments.
