description
The OP27 and OP37 operational amplifiers
combine outstanding noise performance with
excellent precision and high-speed specifica-
tions. 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.
