TPA0212PWPR

Overview

The TPA0212PWPR is a stereo Class-AB audio power amplifier in a 24-pin PowerPAD TSSOP package. It delivers 2.6 W per channel into 3 Ω loads and operates within a 4.5 V to 5.5 V supply range. The device features four selectable BTL gain settings (2, 6, 12, and 24 V/V) controlled via GAIN0 and GAIN1 pins, with SE mode fixed at 1 V/V for headphone drive. It includes an internal input MUX for line or headphone sources, PC-Beep support, and depop circuitry. Supply current is 6 mA in operation and 150 µA in shutdown.

Feature Summary

• Integrated input multiplexer allows selection between dedicated line and headphone input pairs.
• Internal gain control eliminates external resistors, offering four programmable BTL gain levels.
• Built-in depop circuitry minimizes audible transients during power-up and shutdown sequences.
• PowerPAD thermal enhancement provides high heat dissipation comparable to larger through-hole packages.

Applications

• Notebook computer internal speaker amplification
• Desktop PC line-out stages driving 10 kΩ loads
• Headphone amplifier circuits requiring low distortion

Procurement Notes

Verify the PWP suffix indicates the thermally enhanced 24-pin TSSOP PowerPAD package. Confirm the 'R' suffix denotes tape-and-reel packaging. Ensure the component matches the SLOS284B datasheet revision. Check RoHS compliance status as specified in the manufacturer's documentation.

Selection Notes

Select this amplifier for designs requiring integrated gain control and input switching without external components. The PowerPAD package is suitable for applications needing efficient thermal management in a surface-mount form factor. Consider the fixed 1 V/V gain in SE mode when designing headphone output stages.

Part Context

This component belongs to the TPA0212 family of stereo audio power amplifiers from Texas Instruments. It is designed for portable and desktop audio systems where board space and component count are critical constraints. The device integrates analog signal processing functions typically requiring discrete solutions.

Replacement Considerations

TPA0212PWP is the non-tape-and-reel equivalent in the same package.
