TPA711DGN

Overview

The TPA711DGN is a Texas Instruments audio amplifier in an 8-pin MSOP package. It operates as a Class-AB mono amplifier with single-ended input and differential/single-ended output options. Key electrical parameters include a maximum output power of 0.7 W into an 8 Ohm load, a gain-bandwidth product of 1.4 MHz, and a total harmonic distortion plus noise of 0.55%. The device functions on a single supply voltage ranging from 2.5 V to 5.5 V, with a typical operating current of 1.25 mA. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates high-definition headphone drive capability for clear audio reproduction.
• Features low quiescent current consumption suitable for battery-powered applications.
• Provides flexible output configurations supporting both differential and single-ended loads.

Applications

• Headphone amplification
• Speaker driving

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and green material status per Texas Instruments standards. Confirm the MSOP-8 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for any specific thermal management needs associated with the 0.7 W output capability in your enclosure design.

Selection Notes

Select this component when a compact, low-power mono audio solution is required. The MSOP-8 package offers space efficiency compared to larger formats. Consider the 1.4 MHz bandwidth for adequate audio frequency response. Evaluate the 2.5 V minimum supply voltage against your system's lowest expected battery level to ensure proper operation throughout discharge cycles.
