1. Describe

The LT1112S8#PBF dual op amp enables A New Standard in Combining Low Cost and Excellence Precision specifications. A performance match for the chosen primary grade or outperform competing devices. However, in the design of the LT1112S8#PBF, special emphasis is placed on Optimizing the performance of low-cost plastics and SO Bag. For example, 75µV maximum offset voltage In these low cost packages are the lowest of any dual or Quad non-chopped operational amplifiers. The LT1112S8#PBF also offer a complete set of matched specifications to facilitate their use in such matching Application dependent as two and three op amp instrumentation amplifiers. Another set of specifications is provided at ±1V supplies. This is combined with a low supply current of 320µA per amplifier, allowing the LT1112S8#PBF to be powered by Two almost discharged AA batteries
