The SSM2018T is a professional audio quality VCA designed for high performance volume control systems. It features a 117 dB dynamic range, 0.006% typical THD+N, 140 dB gain range, and more.
The SSM2018T is a laser‑trimmed, trim‑less voltage‑controlled amplifier (VCA) that combines the low noise of Class AB topologies with the low distortion of Class A circuits. It offers a 117 dB dynamic range, 0.006 % typical THD+N at 1 kHz unity gain, and a 140 dB gain range from –100 dB to +40 dB. The device is supplied in 16‑lead plastic DIP and SOIC packages and operates over an industrial temperature range of –40 °C to +85 °C.
The datasheet provides detailed electrical specifications, absolute maximum ratings, thermal characteristics, pin configuration, and typical performance graphs. It also includes application notes for basic VCA configurations, theory of operation, and compensation options, making it a comprehensive reference for designers using the SSM2018T in audio volume‑control systems.
