LT We NOLOGY Operational Amplifier FEATURES DESCRIPTION = Guaranteed max. 0.5uV/C Drift The OP-05 is an internally compensated op-amp = Guaranteed max. 0.6uV pk-pk Noise which provides excellent input offset voltage, low bias = Guaranteed max. 2nA Bias Current current, very high common mode rejection, and low = Guaranteed minimum 114dB CMRR offset voltage drift with temperature when the input offset voltage is externally trimmed to zero. Direct re- placement of similar devices in existing systems can result in significant system performance improvement APPLICATIONS without redesign. The OP-05 is particularly well suited for instrumentation and low signal level applications where precision and stability over time and tempera- ture are important. Internal frequency compensation enhances the OP-05s versatility for a wide variety of precision op-amp uses. Linears advanced design, process and test techniques ensure device perfor- mance as well as reliability. An instrumentation ampli- fier application is shown below. For higher performance requirements see the LT 1001 single pre- Cision op amp and the LT 1002 dual matched precision Op amp series.
