The
G
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
μ
V/V on the individual amplifiers. (2) The
difference is calculated between the matching sides in
μ
V/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
