The OP11 provides four matched 741-type operational amplifiers in a single 14-lead DIP. The OP11 is pin compatible with the LM148 amplifier. The amplifier is matched for common-mode rejection ratio and offset voltage, which is very important in designing instrumentation amplifiers. In addition, the amplifier is designed to have equal positive-going and negative-going slew rates. * Guaranteed VOS: 500 μV maximum * Guaranteed matched CMRR: 94 dB minimum * Guaranteed matched VOS: 750 μV maximum * Low noise
