Linear Systems is a small-to-mid-sized semiconductor manufacturer based in Fremont, California, with a history dating back to 1987. The company focuses on discrete semiconductor components and provides these parts as building blocks for customer-designed systems, serving markets such as automated test equipment, professional audio, medical electronics, military, and test and measurement. It maintains a sizable inventory to enable short lead times and accepts orders without minimum quantities, offering direct replacements for thousands of current and obsolete small-signal discretes originally from legacy suppliers. The business supports both new and existing designs by supplying discrete components that best fit each application. In March 2026, the firm announced an expansion of its SPICE model library to support additional devices, reflecting ongoing work to support design and modeling efforts.
