TABLE 1A: ELECTRICAL CHARACTERISTICS
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 V_OS
during the first 30 days are typically 2.5µV. Refer to the typical
performance curve.
Note 3: Sample tested to an LTPD of 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 0.1Hz 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 specifica-
tions unnulled or when nulled with a pot having a range 8kΩ to 20kΩ.
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 9: V_S = ±15V, V_CM = 0V unless otherwise noted.
Note 10: T_A = 25°C, V_S = ±15V, V_CM = 0V, unless otherwise noted.
