TPA701DGNR

Overview

The TPA701DGNR is a Class-AB mono audio power amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and delivers up to 700 mW of output power into an 8-ohm load at 5 V. The device features a THD+N of 0.55% and draws 1.25 mA during operation. It is housed in an SOIC-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Bridge-tied load (BTL) architecture for efficient low-voltage audio amplification
• Integrated thermal and short-circuit protection mechanisms
• Ultra-low quiescent current in shutdown mode for battery conservation
• Single-supply compatibility with wide voltage input range

Applications

• Portable devices requiring built-in speakers
• Low-voltage consumer audio systems
• Battery-operated multimedia equipment

Procurement Notes

Verify the exact suffix against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required RoHS compliance status and operating temperature range for your specific design environment. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current production status before finalizing procurement.

Selection Notes

Select this component when designing single-supply audio circuits that require moderate power output in a compact form factor. The SOIC-8 package suits applications with limited board space. Consider the 2.5V to 5.5V input range for compatibility with standard battery voltages. Verify that the 8-ohm load impedance aligns with your speaker requirements to achieve the specified power levels.

Part Context

The TPA701DGNR belongs to the TPA701 series of low-voltage audio amplifiers. This series is engineered for portable electronics where power efficiency and small footprint are critical. The 'DG' suffix typically denotes the PowerPAD MSOP or similar enhanced thermal package, while 'NR' indicates reel packaging. It serves as a solution for driving small speakers in mobile devices.

Replacement Considerations

TPA701DR is a verified equivalent variant within the same product family.
