Welcome to Weijie Semiconductor

Touchstone Semiconductor

- Touchstone Semiconductor Inc. creates high-performance analog integrated circuit (IC) solutions that solve critical issues for electronics companies. Our proprietary products offer a unique combination of features and performance that cannot be found elsewhere in the analog market. Our second-source products are pin-compatible and specification identical to competitive offerings, providing an ideal alternative for hard-to-secure sole-sourced products. Founded in 2010, Touchstone is headquartered in Milpitas, Calif. Its investors include Opus Capital and Khosla Ventures.

Our mission at Touchstone Semiconductor is designing cool high-performance Analog ICs that help you solve your customers’ problems. We do this by developing ultra low-power high-performance Analog ICs that reduce power consumption in your products.
