‘Jfet’
An Electronicstalk guide
Start with the news release High-temperature data-transmission system unveiled from Cissoid, which we summarised at the time by saying "Cissoid has unveiled RHEA, a high-temperature data-transmission solution with galvanic isolation of 2.5kV and operating reliably from -55 to 225C. ". Several months prior to that, we featured the news release Texas Instruments op amps have rail-to-rail output from Texas Instruments: "Texas Instruments has introduced three ranges of 36V single-, dual- and quad-operational amplifiers (op amp) with industrial precision. ".
In October 2010, we covered the news from Intersil - take a look at Intersil releases JFET-input operational amplifier which says: "Intersil has introduced a JFET-input operational amplifier for process control analogue input/output, gas or fluid flow sensors and biometric high-impedance buffers for medical instrumentation.".
Take a look also at the news release from Cissoid, Power driver suits high-temperature operation, as well as Analog launches 36V JFET-input operational amp from Analog Devices, and Cissoid announces high temperature bridge driver from Cissoid.
