The SSM2250 is a single-channel 1.5W/stereo 250mW power amplifier designed for use in desktop computers. It features single-supply operation, low shutdown current, PC99 compliance, low distortion, and wide bandwidth.
The SSM2250 audio power amplifier from Analog Devices delivers up to 1 W continuous output in bridge‑tied load (BTL) mode and 90 mW per channel in single‑ended mode. It operates from a single 2.7 V to 6 V supply, features rail‑to‑rail outputs, automatic speaker/headphone switching, and a very low shutdown current.
The device is offered in 10‑lead MSOP (RM) and 14‑lead TSSOP (RU) surface‑mount packages, includes built‑in click‑and‑pop reduction, and meets PC99 audio requirements. Detailed electrical characteristics, pin configurations, and typical application circuits are provided.
