ADI

Analog Devices, Inc.

A maker of high-performance analog and mixed-signal chips, Analog Devices builds the tiny sensors, converters, and power circuits found in cars, factories, phones, and medical gear, selling over 75,000 products to customers in dozens of countries. Two MIT graduates, Ray Stata and Matthew Lorber, started it in 1965 in a Cambridge apartment, naming it for its focus on analog signal processing. The company even invented a MEMS accelerometer—first funded for military use—that made modern airbags smarter and safer.
