The RH37C combines very low noise with excellent preci-

sion 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 applica-

tions. The wafer lots are processed to LTC’s in-house

Class S flow to yield circuits usable in stringent military

applications.

For complete electrical specifications and performance

curves see the OP-27/OP-37 data sheet.
