Overview
The TPA0212PWPG4 is a stereo Class-AB audio power amplifier in a 24-pin thermally enhanced PowerPAD TSSOP package. It delivers 2.6 W per channel into 3-ohm loads and operates with a supply voltage range of 4.5 V to 5.5 V. The device features four selectable BTL gain settings (2, 6, 12, and 24 V/V) controlled by GAIN0 and GAIN1 pins, while SE mode is fixed at 1 V/V. It includes an internal input MUX for headphone or line inputs, PC-Beep functionality, and depop circuitry. Supply current is 6 mA in operation and 150 µA in shutdown.
Feature Summary
- Integrated input multiplexer allows selection between dedicated headphone and line input pairs via the HP/LINE control terminal.
- Internal gain configuration eliminates external resistors, offering four distinct bridge-tied load gain steps selectable via digital control pins.
- Built-in depop circuitry minimizes audible transients during power-up and shutdown sequences.
- PowerPAD thermal management enables high power dissipation in a low-profile surface-mount footprint.
Applications
- Notebook computer internal speaker driving
- Desktop PC line-out stages
- Portable multimedia devices requiring stereo amplification
Procurement Notes
Verify the specific PG4 suffix indicates lead-free and RoHS compliance status against the manufacturer's current documentation. Confirm the PWP package variant matches the required thermal pad soldering specifications for the target PCB layout. Ensure system design accounts for the specified operating temperature range of -40°C to 85°C.
Selection Notes
Select this component when a stereo Class-AB solution with integrated gain control and input switching is required. It is suitable for designs needing minimal external components for gain setting and MUX control. Consider the thermal performance of the PowerPAD package for applications driving low-impedance loads at high power levels.
Part Context
This part belongs to the TPA0212 family of stereo audio power amplifiers. The TPA0212PWP is the standard non-RoHS version, while the TPA0212PWPR offers the same electrical characteristics in a tape-and-reel packaging format for automated assembly.

FAQ
How is the amplifier gain configured?
Gain is set internally using the GAIN0 and GAIN1 input terminals. These pins allow selection of four BTL gain values: 2, 6, 12, and 24 V/V. In Single-Ended (SE) mode, the gain is fixed at 1 V/V.
What is the function of the HP/LINE terminal?
The HP/LINE terminal controls the internal input multiplexer. Holding it high activates the headphone inputs (LHPIN/RHPIN), while holding it low activates the line inputs (LLINEIN/RLINEIN).
