OP37G General 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 main-tained 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.
