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.
