Hello, I'm searching for a space grade/rad hard, low noise (<5nV/rtHz), high bandwidth opamp (>100 MHz) for cryogenic operation. SiGe opamps are generally known to perform favorably at cryogenic temperatures. At first glance the RHF350A has good spec...

Hello, Recent testing of the RHF1401 ADC with the internal voltage reference option has shown better performance than with our external reference. However, in section 3.5.2 (p. 26) of the datasheet there is a suggestion that an external reference may...
