LT1057/LT1058
Dual and Quad, JFET Input
Precision High Speed Op Amps
FEATURES
DESCRIPTION
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.

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 4: Current noise is calculated from the formula:
1/2
i = (2ql )
where q = 1.6 • 10
n
b
–19
coulomb. The noise of source resistors up to 1G
swamps the contribution of current noise.
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 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.
Note 3: This parameter is tested on a sample basis only.

LT1057/LT1058
APPLICATIONS INFORMATION
Settling time is measured in a test circuit which can be
found in the LT1055/LT1056 data sheet and in Application
Note 10.
Offset voltage also changes somewhat with temperature
cycling. The AM grades show a typical 40μV hysteresis
(50μV on the M grades) when cycled over the –55°C to
125°Ctemperaturerange.Temperaturecyclingfrom0°Cto
70°C has a negligible (less than 20μV) hysteresis effect.
Achieving Picoampere/Microvolt Performance
Inordertorealizethepicoampere/microvoltlevelaccuracy
of the LT1057/LT1058, proper care must be exercised. For
example, leakage currents in circuitry external to the op
amp can significantly degrade performance. High quality
insulation should be used (e.g., TeflonTM, Kel-F); cleaning
of all insulating surfaces to remove fluxes and other resi-
dues will probably be required. Surface coating may be
necessary to provide a moisture barrier in high humidity
environments.
The offset voltage and drift performance are also affected
by packaging. In the plastic N package, the molding com-
pound is in direct contact with the chip, exerting pressure
on the surface. While NPN input transistors are largely
unaffected by this pressure, JFET device drift is degraded.
Consequently for best drift performance, as shown in the
TypicalPerformanceCharacteristicsdistributionplots, the
J or H packages are recommended.
In applications where speed and picoampere bias currents
are not necessary, Linear Technology offers the bipolar
input, pin compatible LT1013 and LT1014 dual and quad
op amps. These devices have significantly better DC
specifications than any JFET input device.
Board leakage can be minimized by encircling the input
circuitry with a guard ring operated at a potential close to
that of the inputs; in inverting configurations, the guard
ringshouldbetiedtoground,innoninvertingconnections,
to the inverting input. Guarding both sides of the printed
circuit board is required. Bulk leakage reduction depends
on the guard ring width.
Phase Reversal Protection
Most industry standard JFET input single, dual and quad
op amps (e.g., LF156, LF351, LF353, LF411, LF412,
The LT1057/LT1058 have the lowest offset voltage of any
dualandquadJFETinputopampsavailabletoday.However, OP-15, OP-16, OP-215, TL084) exhibit phase reversal at
theoffsetvoltageanditsdriftwithtimeandtemperatureare
still not as good as on the best bipolar amplifiers (because
the transconductance of FETs is considerably lower than
that of bipolar transistors). Conversely, this lower trans-
conductance is the main cause of the significantly faster
speed performance of FET input op amps.
the output when the negative common mode limit at the
input is exceeded (i.e., below –12V with 15V supplies).
The photos below show a 16V sine wave input (A), the
response of an LF412A in the unity gain follower mode
(B), and the response of the LT1057/LT1058 (C).
The phase reversal of photo (B) can cause lock-up in servo
systems. The LT1057/LT1058 does not phase-reverse due
to a unique phase reversal protection circuit.
