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.
