This file is tpa6132a2's datasheet, it is a 25mw headphone amplifier, it can connect single ended or differential input, the output power is 2.3v-5.5v, it has acoustic shock prevention function
The TPA6132A2 is a DirectPath™ stereo headphone amplifier that eliminates the need for external DC‑blocking capacitors. It offers fully differential or single‑ended inputs, built‑in resistors to reduce component count, and selectable gain settings of -6 dB, 0 dB, 3 dB, or 6 dB. The device delivers up to 25 mW into 16 Ω headphones from a 2.3 V supply while maintaining low supply current (2.1 mA typical) and high PSRR.
Typical applications include smartphones, notebook computers, MP3 players and portable gaming devices. The amplifier includes active click‑and‑pop suppression, short‑circuit and thermal‑overload protection, and +8 kV HBM ESD protection, making it suitable for compact audio designs.
