TABLE 1A: ELECTRICAL CHARACTERISTICS

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 8k

Ω to 20kΩ.

Note 8: The RH37C’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: VS = ±15V, VCM = 0V unless otherwise noted.

Note 10: TA = 25°C, VS = ±15V, VCM = 0V, unless otherwise noted.

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 average trend

line of offset voltage vs time over the first 30 days of operation. Excluding

the initial hour of operation, changes in VOS during the first 30 days are

typically 2.5

µV. Refer to the typical performance curves.

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.
