LT1112/LT1114  
Dual/Quad Low Power  
Precision, Picoamp Input Op Amps  
U
FEATURES  
DESCRIPTIO  
The LT®1112 dual and LT1114 quad op amps achieve a  
new standard in combining low cost and outstanding  
precision specifications.  
■
Offset Voltage – Prime Grade: 60µV Max  
Offset Voltage – Low Cost Grade  
■
(Including Surface Mount Dual/Quad): 75µV Max  
■
Offset Voltage Drift: 0.5µV/°C Max  
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.  
■
Input Bias Current: 250pA Max  
■
0.1Hz to 10Hz Noise: 0.3µVP-P, 2.2pAP-P  
■
Supply Current per Amplifier: 400µA Max  
■
CMRR: 120dB Min  
■
Voltage Gain: 1 Million Min  
■
Guaranteed Specs with ±1.0V Supplies  
■
Guaranteed Matching Specifications  
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.  
■
SO-8 Package – Standard Pinout  
■
LT1114 in Narrow Surface Mount Package  
U
APPLICATIO S  
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.

Note 3: Typical parameters are defined as the 60% yield of parameter  
distributions of individual amplifiers; i.e., out of 100 LT1114s (or 100  
LT1112s) typically 240 op amps (or 120) will be better than the indicated  
specification.  
Note 1: Stresses beyond those listed under Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to any Absolute  
Maximum Rating condition for extended periods may affect device  
reliability and lifetime.  
Note 2: Differential input voltages greater than 1V will cause excessive  
current to flow through the input protection diodes unless limiting  
resistance is used.  
Note 4: This parameter is guaranteed by design and is not tested.

LT1114S are guaranteed to meet specified performance from 0°C to 70°C  
and are designed, characterized and expected to meet specified  
performance from –40°C to 85°C, but are not tested or QA sampled at

measured at the minimum supply voltage.  
Note 6: Matching parameters are the difference between amplifiers A and  
D and between B and C on the LT1114; between the two amplifiers on the  
LT1112.  
Note 7: This parameter is the difference between two noninverting input  
bias currents.  
Note 8: ∆CMRR and ∆PSRR are defined as follows: (1) CMRR and PSRR  
are measured in µV/V on the individual amplifiers. (2) The difference is  
calculated between the matching sides in µV/V. (3) The result is converted  
to dB.

The LT1112 dual and LT1114 quad in the plastic and  
ceramic DIP packages are pin compatible to and directly  
replace such precision op amps as the OP-200, OP-297,  
AD706 duals and OP-400, OP-497, AD704 quads with  
improved price/performance.  
output clips cleanly, without any glitches or phase rever-  
sal. The OP-297 exhibits phase reversal. The photos also  
illustrate that both the input and output ranges of the  
LT1112 are within 800mV of the supplies. The effect of  
inputandoutputoverdriveontheotheramplifiersinthe  
LT1112 or LT1114 packages is negligible, as each  
amplifier is biased independently.  
The LT1112 in the S8 surface mount package has the  
standard pin configuration, i.e., the same configuration as  
the plastic and ceramic DIP packages.  
Advantages of Matched Dual and Quad Op Amps  
The LT1114 quad is offered in the narrow 16-pin surface  
mount package. All competitors are in the wide 16-pin  
package which occupies 1.8 times the area of the narrow  
package. The wide package is also 1.8 times thicker than  
the narrow package.  
In many applications the performance of a system de-  
pendsonthematchingbetweentwooperationalamplifiers  
rather than the individual characteristics of the two op  
amps. Two or three op amp instrumentation amplifiers,  
tracking voltage references and low drift active filters are  
some of the circuits requiring matching between two op  
amps.  
TheinputsoftheLT1112/1114areprotectedwithback-to-  
back diodes. In the voltage follower configuration, when  
the input is driven by a fast large-signal pulse (>1V), the  
input protection diodes effectively short the output to the  
input during slewing, and a current, limited only by the  
output short-circuit protection, will flow through the  
diodes.  
The well-known triple op amp configuration illustrates  
theseconcepts.Outputoffsetisafunctionofthedifference  
between the offsets of the two halves of the LT1112. This  
error cancellation principle holds for a considerable num-  
ber of input referred parameters in addition to offset  
voltage and its drift with temperature. Input bias current  
will be the average of the two noninverting input currents  
The use of a feedback resistor is recommended because  
this resistor keeps the current below the short-circuit  
limit,resultinginfasterrecoveryandsettlingoftheoutput.

(IB ). The difference between these two currents (∆IB ) is  
the offset current of the instrumentation amplifier. Com-  
mon mode and power supply rejections will be dependent  
only on the match between the two amplifiers (assuming  
perfect resistor matching).  
The input voltage of the LT1112/1114 should never ex-  
ceed the supply voltages by more than a diode drop.  
However, the example below shows that as the input  
voltage exceeds the common mode range, the LT1112’s

This difference is explained by the fact that capacitance  
betweenadjacentpinsonanICpackageisabout0.25pF  
(including package, socket and PC board trace capaci-  
tances).

The concepts of common mode and power supply rejec-  
tion ratio match (∆CMRR and ∆PSRR) are best demon-  
strated with a numerical example:  
On the dual op amp package, positive input A is next to the  
V– pin (AC ground), while positive input B has no AC  
ground pin adjacent to it, resulting in a 0.25pF input  
capacitance mismatch. At 100Hz, 0.25pF represents a  
6.4 • 109 input impedance mismatch, which is only 76dB  
higher than the 1MΩ source resistors.  
Assume CMRRA = +1µV/V or 120dB,  
and CMRRB = +0.75µV/V or 122.5dB,  
then ∆CMRR = 0.25µV/V or 132dB;  
if CMRRB = –0.75µV/V which is still 122.5dB,  
then ∆CMRR = 1.75µV/V or 115dB.  
On the quad package, all four inputs are adjacent to a  
power supply terminal—therefore, there is no mismatch.  
ClearlytheLT1112/LT1114,byspecifyingandguarantee-  
ing all of these matching parameters, can significantly  
improve the performance of matching-dependent  
circuits.
