LT1057/LT1058
Dual and Quad, JFET Input
Precision High Speed Op Amps
U
FEATURES
DESCRIPTIO
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
inputdualopamps.Inparticular,theLT1057upgradesthe
performance of systems using the LF412A and OP-215
JFET input duals.

14V/µs Slew Rate: 10V/µs Min
■
5MHz Gain-Bandwidth Product
■
Fast Settling Time: 1.3µs to 0.02%
■
150µV Offset Voltage (LT1057): 450µV Max
■
180µV Offset Voltage (LT1058): 600µV Max
■
2µV/°C VOS Drift: 7µV/°C Max
■
50pA Bias Current at 70°C
■
Low Voltage Noise:
The LT1058 is the lowest offset quad JFET input
operationalamplifierinthestandard14-pinconfiguration.
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.

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 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
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.
Note 3: This parameter is tested on a sample basis only.

The LT1057 may be inserted directly in LF353, LF412,
LF442, TL072, TL082 and OP-215 sockets. The LT1058
plugs into LF347, LF444, TL074 and TL084 sockets. Of
course, all standard dual and quad bipolar op amps can
also be replaced by these devices.
with RS and RF in the kilohm range, this pole can create
excess phase shift and even oscillation. A small capacitor
(CF) in parallel with RF eliminates this problem. With
RS(CS + CIN) = RFCF, the effect of the feedback pole is
completely removed.

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°C temperature range. Temperature cycling from 0°C
to 70°C has a negligible (less than 20µV) hysteresis effect.
Achieving Picoampere/Microvolt Performance
Inordertorealizethepicoampere/microvoltlevelaccuracy
oftheLT1057/LT1058, propercaremustbeexercised. 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
residueswillprobablyberequired.Surfacecoatingmaybe
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
compound 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 Typical Performance Characteristics distri-
bution plots, the J or H packages are recommended.
Inapplicationswherespeedandpicoamperebiascurrents
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
ring should be tied to ground, in noninverting connec-
tions, 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,
OP-15, OP-16, OP-215, TL084) exhibit phase reversal at
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
responseofanLF412Aintheunitygainfollowermode(B),
and the response of the LT1057/LT1058 (C).
The LT1057/LT1058 have the lowest offset voltage of
any dual and quad JFET input op amps available today.
However, the offset voltage and its drift with time and
temperature are still not as good as on the best bipolar
amplifiers (because the transconductance of FETs is
considerably lower than that of bipolar transistors).
Conversely,thislowertransconductanceisthemaincause
of the significantly faster speed performance of FET input
op amps.
Thephasereversalofphoto(B)cancauselock-upinservo
systems. The LT1057/LT1058 does not phase-reverse
due to a unique phase reversal protection circuit.
