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.
