ABLIC started its analog semiconductor business in 1968 with the development of CMOS ICs for the world's first mass-produced quartz watches. ABLIC has been playing an important role in the analog semiconductor business, one of the 8 spears, with its strength in product development utilizing "advanced analog technology that realizes small size and low power consumption," providing high-precision analog and mixed signal semiconductors to customers in the fields of automotive, medical equipment, industrial equipment, and consumer electronics.
