DESCRIPTION
The OPA27 and OPA37 are ultra-low noise, high-precision
monolithic operational amplifiers.
Laser-trimmed thin-film resistors provide excellent long-term
voltage offset stability and allow superior voltage offset
compared to common zener-zap techniques.
A unique bias current cancellation circuit allows bias and
offset current specifications to be met over the full 55
C to
+125
C temperature range.
The OPA27 is internally compensated for unity-gain stability.
The decompensated OPA37 requires a closed-loop gain
5.
The Texas Instrument OPA27 and OPA37 are improved
replacements for the industry-standard OP-27 and OP-37.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

APPLICATIONS INFORMATION
OFFSET VOLTAGE ADJUSTMENT
The OPA27 and OPA37 offset voltages are laser-trimmed
and require no further trim for most applications. Offset
voltage drift will not be degraded when the input offset is
nulled with a 10k
trim potentiometer. Other potentiometer
values from 1k
to 1M
can be used, but V
OS
drift will be
degraded by an additional 0.1
V/
C to 0.2
V/
C. Nulling
large system offsets by use of the offset trim adjust will
degrade drift performance by approximately 3.3
V/
C per
millivolt of offset. Large system offsets can be nulled without
drift degradation by input summing.
The conventional offset voltage trim circuit is shown in Figure
3. For trimming very small offsets, the higher resolution
circuit shown in Figure 4 is recommended.
The OPA27 and OPA37 can replace 741-type operational
amplifiers by removing or modifying the trim circuit.
THERMOELECTRIC POTENTIALS
The OPA27 and OPA37 are laser-trimmed to microvolt-level
input offset voltages, and for very-low input offset voltage
drift.
Careful layout and circuit design techniques are necessary to
prevent offset and drift errors from external thermoelectric
potentials. Dissimilar metal junctions can generate small
EMFs if care is not taken to eliminate either their sources
(lead-to-PC, wiring, etc.) or their temperature difference (see
Figure 11).
Short, direct mounting of the OPA27 and OPA37 with close
spacing of the input pins is highly recommended. Poor layout
can result in circuit drifts and offsets which are an order of
magnitude greater than the operational amplifier alone.

COMPENSATION
Although internally compensated for unity-gain stability, the
OPA27 may require a small capacitor in parallel with a
feedback resistor (R
F
) which is greater than 2k
. This ca-
pacitor will compensate the pole generated by R
F
and C
IN
and eliminate peaking or oscillation.
INPUT PROTECTION
Back-to-back diodes are used for input protection on the
OPA27 and OPA37. Exceeding a few hundred millivolts differ-
ential input signal will cause current to flow, and without
external current limiting resistors, the input will be destroyed.
Accidental static discharge, as well as high current, can dam-
age the amplifier's input circuit. Although the unit may still be
functional, important parameters such as input offset voltage,
drift, and noise may be permanently damaged, as will any
precision operational amplifier subjected to this abuse.
Transient conditions can cause feedthrough due to the amplifier's
finite slew rate. When using the OPA27 as a unity-gain buffer
(follower) a feedback resistor of 1k
is recommended, as
shown in Figure 6.
NOISE: BIPOLAR VERSUS FET
Low-noise circuit design requires careful analysis of all noise
sources. External noise sources can dominate in many
cases, so consider the effect of source resistance on overall
operational amplifier noise performance. At low source im-
pedances, the lower voltage noise of a bipolar operational
amplifier is superior, but at higher impedances the high
current noise of a bipolar amplifier becomes a serious liabil-
ity. Above about 15k
, the OPA111 low-noise FET opera-
tional amplifier is recommended for lower total noise than the
OPA27, as shown in Figure 5.

B. OP-07AH with circuit well-shielded from air
currents and RFI.
C. OPA27AJ with circuit well-shielded from air
currents and RFI. (Represents ultimate
OPA27 performance potential.)
D. OPA27 with circuit unshielded and exposed
to normal lab bench-top air currents.
(External thermoelectric potentials far
exceed OPA27 noise.)
E. OPA27 with heat sink and shield which
protects input leads from air currents.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - May not be currently available - please check
http://www.ti.com/productcontent
for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
