TPA311DGNR

Overview

The TPA311DGNR is a mono audio power amplifier in an 8-pin PowerPAD MSOP package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V. The device supports both Bridge-Tied Load (BTL) and Single-Ended (SE) output configurations. In BTL mode with an 8-ohm load, it delivers up to 700 mW at 5 V and 350 mW at 3.3 V. In SE mode, it provides 300 mW at 5 V and 250 mW at 3.3 V into an 8-ohm load. The unity-gain bandwidth is 1.4 MHz, and the shutdown current is as low as 60 µA at 5 V.

Feature Summary

Switchable between bridge-tied load and single-ended modes via a control pin
Integrated depop circuitry to eliminate speaker noise during startup and shutdown
Built-in thermal overload and short-circuit protection for reliability

Applications

Low-voltage portable electronic devices
Internal speaker amplification in handheld equipment
External earphone drive applications

Procurement Notes

Verify the specific ordering suffix 'R' indicates tape and reel packaging when sourcing. Confirm the 'G' suffix corresponds to the RoHS-compliant and halogen-free status required by your manufacturing standards. Ensure the PowerPAD MSOP-8 footprint matches your PCB design guidelines for thermal dissipation.

Selection Notes

Select this component for designs requiring minimal external components due to integrated biasing and protection. The PowerPAD MSOP package offers significant board space reduction compared to standard SOIC packages. Consider the BTL configuration for higher power efficiency in battery-operated systems where coupling capacitors are undesirable.

Part Context

This part belongs to the TPA311 series of Class-AB audio amplifiers designed specifically for low-voltage operation. It is manufactured by Texas Instruments and is characterized for industrial temperature ranges. The device is optimized for voice band frequencies and narrow-band applications typical in cellular communications and portable media players.
