This document introduces the characteristics of TPA6100A2D, including working voltage range, output power, supply current, shutdown current, package type, etc.
The TPA6100A2D is an ultra‑low‑voltage stereo headphone audio power amplifier offered in 8‑pin SOIC and MSOP packages. It delivers up to 50 mW continuous RMS power per channel into 16 Ω loads while consuming only 0.75 mA typical supply current and 50 nA shutdown current, making it ideal for battery‑powered applications.
The datasheet includes detailed electrical characteristics, absolute maximum ratings, recommended operating conditions, and extensive application notes such as gain‑setting resistor calculations, power‑supply decoupling, and capacitor selection. Packaging options, mechanical dimensions, and regulatory notices are also provided.
