History.
The company was incorporated in Tucson, Arizona in 1956 by founders Page Burr (Princeton 1944) and Thomas R. Brown Jr. (BS MIT 1949, MBA Harvard 1952) to commercialize semiconductor transistors; in 1959, the company posted its first profit. Brown eventually bought out Burr's share of the company.
In 1983, the company reincorporated in Delaware, and went public with stock trading on NASDAQ under the symbol BBRC.
The company employed over 1,300 people worldwide with manufacturing and technical facilities located in Tucson, Arizona; Atsugi, Japan; and Livingston, Scotland. Company headquarters was located in Tucson.
Burr-Brown was one of the principal suppliers of precision analog and data acquisition products to the electronic industry. The company pioneered many analog semiconductor products and techniques, such as active laser-trimming.
