NOTES: (1) Packages must be derated based on _JC = 150/W or _JA = 300/W. (2) For supply voltages less than ±18VDC, the absolute maximum input voltage is equal to +18V > V_IN > V_CC 6V. See Figure 2. (3) Short circuit may be to power supply common only. Rating applies to +25 ambient. Observe dissipation limit and T_J.

The OPA111 is a precision monolithic dielectrically isolated FET (Difet ^®) operational amplifier. Outstanding performance characteristics allow its use in the most critical instrumentation applications.

Noise, bias current, voltage offset, drift, open-loop gain, common-mode rejection, and power supply rejection
are superior to BIFET^® amplifiers.

Very low bias current is obtained by dielectric isolation with on-chip guarding.

Laser trimming of thin-film resistors gives very low offset and drift. Extremely low noise is achieved with patented circuit design techniques. A new cascode design allows high precision input specifications and reduced susceptibility to flicker noise.

Standard 741 pin configuration allows upgrading of existing designs to higher performance levels.
