ssm2315 is a highly efficient filterless class-d audio amplifier from analog devices, inc. it supports single-supply operation, 3ω and 8ω loads, and a working voltage range of 2.5v-5.5v. it also features ultralow shutdown current, short-circuit protection, and thermal protection.
The SSM2315 is a filterless, high‑efficiency Class‑D audio amplifier designed for mobile phone and portable electronics applications. It operates from a single 2.5 V to 5.5 V supply and provides up to 3 W continuous output into a 3 Ω load while maintaining <1 % total harmonic distortion.
The device includes built‑in pop‑and‑click suppression, short‑circuit and thermal protection, and a default 6 dB gain that can be adjusted with external resistors. Detailed specifications, pin descriptions, layout guidelines, and ordering information are provided in the document.
| Output Power (8 Ω, 5 V) | 1.4 W |
