Raytheon Quad OpAmp

Raytheon sold its semiconductor operations in Mountain View CA to Fairchild in 1997. Fairchild was then a re-incarnation, not the original Silicon Valley pioneer. Raytheon had originally purchased Mountain View's Rheem in 1959, two years after it had spun out from Fairchild, led by Ed Baldwin who had moved from Hughes Semiconductors to Fairchild. Raytheon was expanding its transistor manufacturing into California through the acquisition. Like many companies, Raytheon expanded into bipolar and MOS circuits.
Cyrus Madavi, who led Burr-Brown through to acquisition by TI came from Raytheon.
I worked for Hughes, Raytheon and Burr-Brown.

Burr-Brown PCM1702 A Really Interesting Audio DAC From the 90s

Image
Burr-Brown PCM1702-L I've just acquired from eBay a CD player to complement another very old CD player, both with Burr-Brown Digital to Analog converters. The photo shows the inside of the Denon CD-655 from the late 90s, a super low distortion and high signal to noise ratio CD player which uses 2 x PCM1702 DACs from Burr-Brown. The BiCMOS process 20-Bit PCM1702 was a really interesting DAC which was an improved version of the PCM63P. Early R-2R ladder DACs suffered from some noise/glitches at low output levels (and degraded linearity) due to the Most Significant Bit current source turning on at the lowest volume output point. Multi-bit DACs had significantly higher performance than contemporary 1-bit and "MASH" DACs, but had this one flaw. The PCM1702 was effectively two 19-bit DACs in a complementary design which negated the zero cross point issue. They had all the benefits of R-2R ladder DACs and now removed the other issue. Around this time Burr-Brown were al...

Fairchild Micrologic - The World's First Integrated Circuits

Image
Fairchild Micrologic Devices Fairchild introduced the Micrologic standard logic family in 1961. These were the world's first ICs, based on Jean Hoerni's revolutionary planar process which laid the blueprint for all future integrated circuits. There were eventually 25 standard logic RTL ICs. Products in the family included the 900, a buffer, 901, a 3 gate counter adapter, the 902, a flip-flop, 923, a JK flip flop and the 959, a 4bit latch. Above is a  3-input NOR device from the early 60s (uL903) in a metal can, and a later packaged JK flip flop (uL923) in a lower cost epoxy topped package. During the 1960s, Fairchild became the first semiconductor company to establish a lower cost assembly facility in the Far East (Hong Kong). Decapped uL903 Micrologic Device The 3-input NOR from Fairchild became the basic building block of the Apollo guidance computer, designed by MIT and built by Raytheon. It used 5,000 3-input NOR ICs and was the first major application of ICs. ...

Fairchild Semiconductor's First Product

Image
Double diffused base silicon mesa transistor 2N697, Fairchild's first product was launched commercially at the Wescon show in August 1958. Fairchild's first product was a commercial success due to its benefits over other transistors on the market. IBM were Fairchild's first customer, using the 2N697 as a ferrite core memory driver on the XB-70 avionics contract. IBM paid $150 per transistor for the first order, 30 times the industry price. The Fairchild 2N697 was silicon, hence it had high temperature benefits over germanium and had lower power dissipation than other silicon equivalents, due to Fairchild's diffusion process. Fairchild Semiconductor (in the late 50s and 60s) were one of the most innovative and influential companies in semiconductor history, developing the planar process and the first integrated circuits.
