Analog Devices OP77

The OP77 has outstanding gain of 10,000,000 or more that is maintained over the full 10 V 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. These characteristics, plus the TCVOS of 0.3 μV/°C maximum and the low VOS of 25 μV maximum, eliminates VOS TRIM VOS TRIM 8 V+ 1 OP77 7 –IN 2 6 OUT 35 +IN 4 NC 4V– (CASE) TOP VIEW (Not to Scale) NC = NO CONNECT Figure 2.

GENERAL DESCRIPTION

Low initial VOS drift and rapid stabilization time, combined with only 50 mW of power consumption, are significant improvements over previous designs. TO-99 (J Suffix) 00320-002 the need for VOS adjustment and increases system accuracy over temperature. A PSRR of 3 μV/V (110 dB) and CMRR of 1.0 μV/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.
