description

® The LT 1112's dual and LT1114 quad operational amplifiers set a new standard in combining low cost and excellent accuracy metrics.

The selected Premier grades meet or exceed the performance of competing devices. The LT1112/LT1114 design, however, has placed special emphasis on optimizing low-cost plastic and SO packaging performance. For example, the 75μV maximum offset voltage is the lowest non-kitchen knife of any dual-core or quad op-amp on these low-cost packages.

The LT1112/LT1114 also provides a full set of companion specifications to facilitate the use of companion applications such as triple op amp instrumentation amplifiers.

Another set of specifications is arranged in ± 1V supplies. This, combined with a low supply current of 320μA per amplifier, allows the LT1112/LT1114 to be powered by two AA batteries near-discharge.
