Overview
The TDA7491P13TR is a dual BTL Class-D audio amplifier manufactured by STMicroelectronics, designed for LCD TVs and monitors. It operates on a single power supply ranging from 5V to 18V. The device delivers 10W + 10W continuous output power at VCC = 11V with RL = 6Ω and THD = 10%, or 9.5W + 9.5W at VCC = 12V with RL = 8Ω and THD = 10%. It features high efficiency of 90% and filterless operation. The component is housed in a PowerSSO-36 EPD package.
Feature Summary
- Filterless operation reduces external component count
- Differential inputs minimize common-mode noise
- No pop sound during turn-on/off transitions
- Externally synchronizable for multi-amplifier systems
Applications
- LCD televisions
- Computer monitors
Procurement Notes
Verify the specific suffix '13TR' against the manufacturer's official datasheet to confirm it denotes the tape-and-reel packaging variant of the TDA7491P. Ensure the ordering information matches the exact PowerSSO-36 EPD package type required for the design. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before procurement.
Selection Notes
Select this component when designing stereo audio systems requiring high efficiency without separate heatsinks. It is suitable for applications needing differential input noise rejection and fixed gain settings of 20dB, 26dB, 30dB, or 32dB. Consider its pin-to-pin compatibility with TDA7491LP and TDA7491HV if upgrading existing designs.
Part Context
This part belongs to the TDA7491 family of Class-D audio amplifiers from STMicroelectronics. The family includes variants like TDA7491P, TDA7491LP, and TDA7491HV, which share pin compatibility but differ in output power capabilities and package types (EPD vs EPU). The TDA7491P specifically targets 10W+10W applications in consumer electronics.
Replacement Considerations
The TDA7491P13TR is pin-to-pin compatible with the TDA7491LP and TDA7491HV series. Designers can substitute these parts directly if the power requirements and package variations align with the system specifications.
