The ● denotes specifications which apply over the operating temperature
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.
