Overview
The TDA7498E is a dual BTL Class-D audio amplifier designed for home systems and active speakers. It operates on a single supply of 14V to 36V, delivering 160W + 160W at THD=10% with RL=4Ω and VCC=36V. In mono parallel BTL mode (RL=3Ω), it provides 220W output. The device features high efficiency (85%), differential inputs, standby/mute controls, and smart protection including thermal overload. It utilizes a 36-pin PowerSSO package with an exposed pad.
Feature Summary
- Dual BTL architecture supporting stereo or mono parallel BTL configurations via the MODE pin
- High-efficiency power conversion with integrated smart protection mechanisms
- Differential input design to minimize common-mode noise interference
- Selectable fixed gain settings and dedicated standby and mute control functions
Applications
- Home audio systems
- Active speaker applications
- High-fidelity sound reproduction setups
Procurement Notes
Verify the specific ordering suffix against official STMicroelectronics documentation to confirm packaging type, as standard tubes and tape-and-reel variants exist. Ensure the component matches the required operating temperature range and environmental compliance standards specified in the datasheet before procurement.
Selection Notes
Select this amplifier for designs requiring high output power within a compact form factor. Consider the 36-pin PowerSSO package requirements for adequate thermal management and heatsink mounting. Verify that the application supports the wide-range single-supply voltage operation and utilizes differential inputs to maximize signal integrity.
Part Context
Manufactured by STMicroelectronics, the TDA7498E belongs to the company's line of high-performance analog audio amplifiers. Released in June 2015, it serves as a robust solution for demanding audio environments where efficiency and power density are critical design parameters.
Replacement Considerations
Consult official manufacturer substitution lists for verified alternatives. Cross-reference pinouts and electrical specifications carefully when evaluating potential replacements to ensure compatibility with existing circuit designs.
