Overview
The TDA7495 is a stereo Class AB power amplifier designed for high-quality sound TV applications. It delivers 11W per channel at 8Ω with THD=10% and VS=28V, or 8W at 1Ω with THD=1%. The device operates on a single supply ranging from 11V to 35V. Key features include linear volume control via DC coupled power op amp, mute and stand-by functions, low turn-on/off pop noise, and internally fixed gain. Protection mechanisms include short-circuit and thermal overload safeguards.
Feature Summary
- Linear volume control integrated with DC coupled power operational amplifier
- Low turn-on and turn-off pop noise performance
- Integrated mute and stand-by functions for power management
- Short-circuit and thermal overload protection
Applications
- High quality sound TV applications
- Audio systems requiring linear volume control
- Single supply audio amplification circuits
Procurement Notes
Verify the exact package type and manufacturer date code upon receipt. Confirm that the component matches the Multiwatt 15 outline dimensions. Check for any physical damage to the pins before installation. Ensure proper thermal management is implemented as specified in the datasheet thermal data section.
Selection Notes
Select this component for designs requiring integrated volume control without external Boucherot cells. It is suitable for applications needing a single supply voltage up to 35V. Consider the thermal resistance values when designing the heatsink. Verify input signal levels against the maximum input voltage rating of 8 Vpp.
Part Context
This part belongs to the TDA74xx series of audio amplifiers by STMicroelectronics. It utilizes MULTIPOWER BI50II technology. The device is housed in a Multiwatt 15 vertical package with bent and staggered leads. It is designed specifically for television and similar audio equipment where space and component count are considerations.
Replacement Considerations
The TDA7496SA is pin-to-pin compatible with the TDA7495. Other compatible parts in the family include TDA7496, TDA7496S, TDA7495S, and TDA7495SA. Verify specific output power ratings and package variations when substituting.
