Direct re- placement of similar devices in existing systems can result in significant system performance improvement 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 LT1001 single pre- cision op amp and the LT 1002 dual matched precision Op amp Series.
