TPA6211A1DRB

Overview

The TPA6211A1DRB is a mono, fully differential Class-AB audio amplifier manufactured by Texas Instruments. It delivers 3.1 W of output power into a 3-ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and draws a typical quiescent current of 4 mA. It features a fixed gain of 1 V/V and accepts differential inputs. The component is housed in an 8-pin SON package (3x3 mm) and supports surface-mount installation. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fully differential input and output architecture for improved noise rejection
• Integrated pop-and-click suppression circuitry to minimize startup transients
• Thermal shutdown protection to safeguard the device under overload conditions

Applications

• Portable media players and MP3 devices
• Mobile phones and smartphones
• Personal digital assistants (PDAs)
• Handheld gaming consoles

Procurement Notes

Verify the specific suffix DRB corresponds to the tube packaging configuration when ordering. Confirm RoHS compliance status through the manufacturer's official documentation prior to integration. Ensure the design accounts for the 8-SON footprint dimensions and thermal pad requirements for proper heat dissipation during operation.

Selection Notes

Select this component for applications requiring high efficiency and low power consumption in space-constrained portable electronics. The fixed unity gain simplifies circuit design by eliminating external feedback resistors. Consider the thermal performance of the PCB layout to maintain reliability within the specified operating temperature range.

Part Context

This part belongs to the TPA6211A1 family of mono audio amplifiers designed for battery-powered devices. It shares core electrical specifications with variants such as the TPA6211A1DRBR, differing primarily in packaging format. The series is optimized for delivering high-quality audio performance while maximizing battery life in consumer electronics.

Replacement Considerations

TPA6211A1DRBR serves as a functional equivalent with identical electrical characteristics but utilizes reel packaging instead of tubes.
