TPA6132A2 Description

Short technical summary and product information.

The Texas Instruments TPA6132A2 is a DirectPath™ stereo headphone amplifier designed for applications requiring high fidelity audio without external DC-blocking capacitors. Its outputs are biased at 0V, contributing to excellent low-frequency performance.

This amplifier operates from a wide power supply range of 2.3V to 5.5V, delivering a constant maximum output power of 25mW into a 16Ω load. It features fully differential or single-ended inputs with built-in resistors to reduce component count and improve system noise performance. Gain is selectable across four settings: -6dB, 0dB, 3dB, and 6dB.

The TPA6132A2 includes active click and pop suppression circuitry, ensuring smooth turn-on and turn-off transitions. It boasts high power supply noise rejection, with 100dB PSRR at 217Hz and 90dB PSRR at 10kHz, along with improved RF noise immunity. The device is protected against short-circuits and thermal overload, and its outputs are ESD protected to ±8kV HBM.

Available in a compact 16-pin, 3mm x 3mm WQFN package, the TPA6132A2 is suitable for space-constrained designs in portable electronics such as smartphones, cellular phones, notebook computers, MP3 players, and portable gaming devices.
