FEATURE
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 75
μ
V 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 320
μ
A supply current per
amplifier, allows the LT1112/LT1114 to be powered by
two nearly discharged AA cells.
