The RH27C combines very low noise with excellent precision and high speed specifications. The low 1/f noise corner frequency of 2.7Hz combined with 3.5nVHz 10Hz noise and low offset voltage make the RH27C 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. For complete electrical specifications and performance curves see the OP-27/OP-37 data sheet.

Note 1: Input offset voltage measurements are performed by automatic test equipment approximately 0.5 seconds after application of power. Note 2: Long-term input offset voltage stability refers to the averaged trend line of offset voltage vs time over extended periods after the first 30 days of operation. Excluding the initial hour of operation, changes in VOS during the first 30 days are typically 2.5µV. Refer to the typical performance curve. Note 3: Sample tested to an LTPD 15 on every lot. Contact factory for 100% testing of 10Hz voltage density noise. Note 4: Parameter is guaranteed by design, characterization, or correlation to other tested parameters. Note 5: See test circuit and frequency response curve for to 10Hz tester on OP-27/OP-37 data sheet. Note 6: See test circuit for current noise measurement on OP-27/OP-37 data sheet. Note 7: The average input offset drift performance is within the specifications unnulled or when nulled with a pot having a range to 20k. Note 8: The RH27C's inputs are protected by back-to-back diodes. Current limiting resistors are not used in order to achieve low noise. If differential input voltage exceeds ± 0.7V, the input current should be limited to 25mA. Note ± 15V, VCM = 0V unless otherwise noted. Note ± 15V, VCM = 0V, unless otherwise noted.
