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
specifications unnulled or when nulled with a pot having a range 8kΩ to
20kΩ.
Note 8: The RH27’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.
Note 11: RH27AEW is marked and processed as RH27EW. Orders will be
delivered through box stock screening at 25°C, –55°C to 125°C to the V_OS
specification shown on Table 1.
