DESCRIPTIO
ABSOLUTE
The RH37C combines very low noise with excellent precision and high speed specifications. The low 1/f noise
corner frequency of 2.7Hz combined with 3.5nV√Hz 10Hz
noise and low offset voltage make the RH37C an excellent
choice for low frequency military instrumentation applications. The wafer lots are processed to LTC’s in-house
Class S flow to yield circuits usable in stringent military
applications.
