OP227
ObsoleteDual, Low-Noise Low-Offset Instrumentation Operational Amplifier
Part Details
The OP-227 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 OP-227 with a VOS match of 25µV typical, a TCVOS match of O.3µV/°C typical, and a 1/f corner of only 2.7Hz is an excellent choice for precision low noise designs. These D.C. characteristics, coupled with a slew rate of 2.8V/µs typical and a small-signal bandwidth of 8MHz typical, allow the designer to achieve AC performance previously unattainable with op-amp-based instrumentation designs.
