RH27C
Precision Operational Amplifier
DESCRIPTIO
The RH27C 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 RH27C 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.
