Характеристики
OP77EZ, DIC8The OP77EZ is an Ultralow Offset Voltage Operational Amplifier with outstanding gain of 10.000.000 or more that is maintained over the full 10V output range. This gain-linearity eliminates incorrectable system nonlinearities common in previous monolithic op amps and provides superior performance in high closed-loop gain applications. Low initial VOS drift and rapid stabilization time, combined with only 50mW of power consumption, are significant improvements over previous designs. These characteristics, plus the TCVOS of 0.3µV/°C maximum and the low VOS of 25µV maximum, eliminates the need for VOS adjustment and increases system accuracy over temperature. A PSRR of 3µV/V (110dB) and CMRR of 1.0µV/V maximum virtually eliminate errors caused by power supply drifts and common-mode signals. This combination of outstanding characteristics makes the OP77 ideally suited for high resolution instrumentation and other tight error budget systems.
