Company Profile
About Trusignal
Trusignal Microelectronics Co., Ltd. was founded in 2011, headquartered in Suzhou Industrial Park with an R&D center in the United States, and is a high-tech enterprise focused on the design and sales of high-performance, high-quality analog and mixed-signal integrated circuits. Its core technical team is made up of senior IC design experts from leading international semiconductor companies, averaging over 20 years of experience. Beyond its Suzhou headquarters it runs an R&D sub-center in Shanghai and sales centers in Beijing, Shenzhen and Zhuhai. Wafer fabrication is handled by PSMC (Taiwan) and SMIC (Shanghai), with assembly and test by JCET (Jiangyin) and Huatian (Tianshui); it is ISO9001-certified and its products comply with EU RoHS and green-manufacturing standards. Its mission is to localize high-performance analog chips and break the dominance of European and American vendors in high-end analog ICs, with a vision to become the leader of China's high-performance analog chip industry.
China-based designer of high-performance analog and mixed-signal ICs, spanning signal-chain (op-amps / comparators / analog switches / voltage references), power management (LDO/DC-DC) and application-specific standard products (pulse-oximeter AFE / IR receivers).
