OP77

下一代OP07超低失调电压运算放大器 Next Generation OP07 Ultralow Offset Voltage Operational Amplifier

Product Details

The significantly advances the state-of-the-art in precision op amps. The outstanding gain of 10,000,000 or more for the OP77 is maintained over the full 10 V output range. This exceptional 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 50 mW of power consumption, are significant improvements over previous designs. These characteristics, plus the exceptional TCVOS of 0.3 μV/°C maximum and the low VOS of 25 μV maximum, eliminates the need for VOS adjustment and increases system accuracy over temperature.

PSRR of 3µV/V 110dB and CMRR of 1.0µV/V maximum virtually eliminates 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.
