TDA7496

Overview

The TDA7496 is a dual-channel Class-AB audio power amplifier manufactured by STMicroelectronics. It supports single-supply operation with typical voltages of 12 V, 15 V, 18 V, 24 V, and 28 V. The device delivers up to 5 W of maximum output power into an 8 Ω load. It features a 15-pin MULTIWATT V package designed for through-hole mounting. The operational temperature range spans from 0 °C to +70 °C.

Feature Summary

• Class-AB amplification topology for stereo audio applications
• Integrated protection mechanisms including thermal overload and short-circuit prevention
• Supports mute, standby, and pop-noise elimination functions

Applications

• Speaker systems
• Automotive audio equipment
• Home theater receivers

Procurement Notes

Verify the specific suffix (e.g., L) against the datasheet to confirm pinout and packaging compatibility. Confirm RoHS3 compliance status for current production units. Check component lifecycle status as some variants may be discontinued. Ensure the MULTIWATT V package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component for designs requiring robust Class-AB performance in automotive or consumer environments. Verify that the 15-pin MULTIWATT V package fits the mechanical constraints. Ensure the supply voltage aligns with the supported 12 V to 28 V range. Consider thermal management solutions given the through-hole package and power dissipation characteristics.

Part Context

The TDA7496 belongs to STMicroelectronics' portfolio of automotive-grade audio power amplifiers. It is part of a broader family including the TDA7490 and TDA7491 series. These devices are engineered for high reliability in vehicle infotainment and sound system applications, offering differential inputs and diagnostic capabilities in newer iterations.
