Overview
The TPA0212PWPRG4 is a stereo audio power amplifier in a 24-pin PowerPAD (PWP) package. It delivers 2.6 W per channel into 3-Ω loads and operates within 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, with SE mode 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 normal operation and 150 µA in shutdown.
Feature Summary
- Integrated input multiplexer allows selection between dedicated headphone and line-level stereo inputs via the HP/LINE control terminal.
- Internal gain configuration eliminates external resistors, providing four distinct bridge-tied load gain levels while maintaining a fixed single-ended gain.
- Built-in depop circuitry minimizes audible transients during power-up and shutdown sequences.
- PowerPAD thermal enhancement provides high heat dissipation capability comparable to larger through-hole packages.
Applications
- Notebook computer internal speaker amplification
- Desktop PC line-out drivers compatible with PC99 standards
- Headphone amplifier circuits
Procurement Notes
Verify the suffix 'R' indicates tape-and-reel packaging and 'G4' denotes lead-free compliance. Confirm the PWP package type matches the required thermal pad soldering specifications. Ensure the operating temperature range of -40°C to 85°C aligns with the target environment. Cross-reference the datasheet revision SLOS284B for accurate electrical characteristics.
Selection Notes
Select this component when a compact stereo amplifier with integrated input switching is required. The fixed single-ended gain simplifies headphone drive designs. Consider the thermal requirements of the PowerPAD package for high-power applications. Verify that the 4.5 V to 5.5 V supply range suits the system battery or rail voltage.
Part Context
This part belongs to the TPA0212 family of stereo audio power amplifiers from Texas Instruments. The TPA0212 series is designed for portable and desktop audio applications requiring high efficiency and low component count. The PWPR variant specifically utilizes the thermally enhanced surface-mount package for improved heat management.
Replacement Considerations
TPA0212PWP is the non-reel equivalent. TPA0212PWPR is the reel version without the G4 suffix. Check datasheet compatibility for pinout and electrical parameters before substitution.
