LT1057/LT1058
10578fa
The LT
®
1057 is a matched JFET input dual op amp in the
industry standard 8-pin configuration, featuring a
combination of outstanding high speed and precision
specifications. It replaces all the popular bipolar and JFET
input dual op amps. In particular, the LT1057 upgrades the
performance of systems using the LF412A and OP-215
JFET input duals.
The LT1058 is the lowest offset quad JFET input
operational amplifier in the standard 14-pin configuration.
It offers significant accuracy improvement over presently
available JFET input quad operational amplifiers. The
LT1058 can replace four single precision JFET input op
amps, while saving board space, power dissipation and
cost.
Both the LT1057 and LT1058 are available in the plastic
PDIP package and the surface mount SO package.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Typical parameters are defined as the 60% yield of distributions of
individual amplifiers; (i.e., out of 100 LT1058s or, 100 LT1057s, typically
240 op amps, or 120 for the LT1057, will be better than the indicated
specification).
Note 3: This parameter is tested on a sample basis only.
Note 4: Current noise is calculated from the formula:
i
n
= (2ql
b
)
1/2
where q = 1.6 · 10
19
coulomb. The noise of source resistors up
to1G swamps the contribution of current noise.
Note 5: This parameter is not 100% tested.
Note 6: Gain-bandwidth product is not tested. It is guaranteed by
design and by inference from the slew rate measurement.
