Feature of OP37 Series:

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.
