TPA741DR

Overview

The TPA741DR is a mono, differential input, Class-AB audio amplifier manufactured by Texas Instruments. It delivers 700 mW of output power and features active high shutdown and depop functionality. The device is housed in an 8-SOIC package with an operating temperature range of -40 to 85 degrees Celsius.

Feature Summary

• Differential input architecture for noise rejection
• Active high shutdown control
• Depop circuitry to minimize startup noise

Applications

• Low-voltage audio power amplification
• Mono audio signal processing
• Portable electronic devices requiring efficient Class-AB amplification

Procurement Notes

Verify the specific suffix DR against official datasheets to confirm the SOIC package and tape-and-reel delivery format. Ensure the voltage ratings and thermal characteristics align with your system requirements before procurement.

Selection Notes

Select this component when a mono, low-voltage solution with differential inputs is required. The integrated shutdown and depop features simplify board design compared to discrete solutions lacking these controls.

Part Context

This part belongs to the TPA741 family of audio amplifiers. Variants include DGNG4 and DGNR, which share similar electrical characteristics but differ in package type, such as MSOP-PowerPAD versus SOIC.

Replacement Considerations

Check for TPA741DGNG4 or TPA741DGNR if MSOP packages are acceptable. Verify pinout compatibility before substituting with other TI mono amplifiers.
