LT1112/LT1114

ESCRIPTIO

Dual/Quad Low Power

Precision, Picoamp Input Op Amps

The LT1112 dual and LT1114 quad op amps achieve a new

standard in combining low cost and outstanding precision

specifications.

The performance of the selected prime grades matches or

exceeds competitive devices. In the design of the LT1112/

LT1114 however, particular emphasis has been placed on

optimizing performance in the low cost plastic and SO

packages. For example, the 75µV maximum offset voltage

in these low cost packages is the lowest on any dual or

quad non-chopper op amp.

The LT1112/LT1114 also provide a full set of matching

specifications, facilitating their use in such matching

dependent applications as two and three op amp instru-

mentation amplifiers.

Another set of specifications is furnished at ±1V supplies.

This, combined with the low 320µA supply current per

amplifier, allows the LT1112/LT1114 to be powered by

two nearly discharged AA cells.
