LM4755TSX/NOPB

Audio Amplifiers Overview

The LM4755TSX/NOPB is a stereo Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 11 W of output power into a 4 Ohm load with a supply voltage range of 9 V to 32 V. The device features a total harmonic distortion plus noise (THD+N) of 0.08%. It operates on a single power supply and includes analog input channels. The component is housed in a TO-263-9 surface-mount package and supports an operating temperature range from -20°C to +80°C.

• Integrated thermal and short-circuit protection mechanisms
• Single-supply operation capability

Audio Amplifiers Applications

• High-power stereo audio systems
• Professional audio equipment
• Home theater receivers

Audio Amplifiers Procurement Notes

Verify the specific suffix 'TSX' against official Texas Instruments documentation to confirm reel packaging and RoHS compliance status, as datasheets may list variations like 'TS'. Confirm current production status, as related packages such as LM4755TS/NOPB have been marked obsolete in some distributor records. Ensure compatibility with required humidity sensitivity levels before procurement.

Audio Amplifiers Selection Notes

Select this component when a robust Class-AB solution is required for stereo applications needing up to 11 W per channel into 4 Ohms. Consider the TO-263-9 package for thermal management needs. Verify that the 9 V to 32 V supply range aligns with system design constraints. Check for alternative packages if different mounting styles are preferred.

Audio Amplifiers Part Context

The LM4755 series represents Texas Instruments' line of high-power audio amplifiers designed for demanding audio environments. This specific part belongs to the broader LM4755 family, sharing core architectural features with variants differing primarily in packaging and minor electrical specifications. It serves as a bridge between lower-power consumer amps and higher-end professional solutions.

Audio Amplifiers Replacement Considerations

Public records indicate TPA3110D2PWP as a similar replacement option for the LM4755TS/NOPB variant. Verify functional equivalence and pinout compatibility before substitution.
