General Description

The OP227 is the first dual amplifier to offer a combination of low offset, low noise, high speed, and guaranteed amplifier matching characteristics in one device.

The OP227, with a VOS match of 25 mV typical, a TCVOS match of 0.3 mV/∞C typical and a 1/f corner of only 2.7 Hz is an excellent choice for precision low noise designs.

These dc characteristics, coupled with a slew rate of 2.8 V/ms typical and a small-signal bandwidth of 8 MHz typical, allow the designer to achieve ac performance previously unattainable with op amp based instrumentation designs.
