TPA6132A2RTER TI Audio Amplifiers

The TPA6132A2RTER is a 25‑mW, stereo, analog input headphone amplifier from Texas Instruments featuring DirectPath™ technology, which eliminates the need for external DC‑blocking output capacitors and biases outputs at 0 V for excellent low‑frequency fidelity. It operates from a 2.3 V to 5.5 V supply with 2.1 mA typical current (shutdown <1 µA). For selection, ensure this supply range matches your system, confirm gain selection via built‑in resistors (‑6 dB, 0 dB, 3 dB, 6 dB), note the 25 mW per channel output into 16 Ω load, and verify the –40 °C to +85 °C industrial operating range. Fully differential or single‑ended inputs, active click‑and‑pop suppression, short‑circuit/thermal protection, ±8 kV HBM ESD protection, and 100 dB PSRR at 217 Hz ensure robust performance. Typical applications include smartphones, notebooks, CD/MP3 players, portable gaming devices, and Bluetooth speakers. In stock at HL Electronics – request a quote for fast delivery.
