range.

Note 1: Differential input voltages greater than 1V will cause excessive

current to flow through the input protection diodes unless limiting

resistance is used.

Note 2: 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 3: This parameter is guaranteed by design and is not tested.

Note 4: Offset voltage, supply current and power supply rejection ratio are

measured at the minimum supply voltage.

Note 5: 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 6: This parameter is the difference between two noninverting

input bias currents.

Note 7:

∆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.

Note 8: This parameter is not 100% tested.

Note 9: These parameters are not tested. More than 99% of the op

amps tested during product characterization have passed the

maximum limits. 100% passed at 1kHz.

Note 10: The LT1112/LT1114 are not tested and are not quality

assurance sampled at – 40

°C and at 85°C. These specifications are

guaranteed by design, correlation and/or inference from – 55

°C, 0°C,

25

°C, 70°C and/or 125°C tests.
