description
The OP27 and OP37 operational amplifiers
combine outstanding noise performance with
excellent precision and high-speed specifications.
The wideband noise is only 3 nV/√Hz and with the
1/f noise corner at 2.7 Hz, low noise is maintained
for all low-frequency applications.
The outstanding characteristics of the OP27 and
OP37 make these devices excellent choices
for low-noise amplifier applications requiring
precision performance and reliability . Additionally ,
the OP37 is free of latch-up in high-gain,
large-capacitive-feedback configurations.
The OP27 series is compensated for unity gain.
The OP37 series is decompensated for increased
bandwidth and slew rate and is stable down to a
gain of 5.
The OP27A, OP27C, OP37A, and OP37C are
characterized for operation over the full military
temperature range of –55°C to 125°C. The
OP27E, OP27G, OP37E, and OP37G are
characterized for operation from – 25°C to 85°C.

NOTES: 1. All voltage values are with respect to the midpoint between VCC+ and VCC– unless otherwise noted.
2. The inputs are protected by back-to-back diodes. Current-limiting resistors are not used in order to achieve low noise. Excessive
input current will flow if a differential input voltage in excess of approximately ± 0.7 V is applied between the inputs unless some
limiting resistance is used.

4. Long-term drift of input of fset voltage refers to the average trend line of of fset voltage versus time over extended periods after the
first 30 days of operation. Excluding the initial hour of operation, changes in VIO during the first 30 days are typically 2.5 µV
(see Figure 3).
