description
® The LT 1112's dual and LT1114 quad op amps achieve a new standard combining low cost with excellent accuracy specifications.
Selected Premier grades meet or exceed competitive performance. However, the LT1112/LT1114 design has placed special emphasis on optimizing low cost plastic and SO package performance. For example, the 75μV maximum offset voltage is the lowest non-chopping knife of any dual-core or quad-op amp on these low-cost packets.
The LT1112/LT1114 also offer a full set of specifications to facilitate use in companion applications such as triple-op-amp instrumentation amplifiers.
Another set of specifications is laid out in ± 1V supplies. This, combined with a low supply current of 320μA per amplifier, makes the LT1112/LT1114 nearly discharged from hospital powered by two AA batteries.
