FEATURES
DESCRIPTION
ꢀ LOW QUIESCENT CURRENT: 175µA/chan.
ꢀ WIDE SUPPLY RANGE: ±1.35V to ±18V
ꢀ LOW OFFSET VOLTAGE: 250µV max
ꢀ LOW OFFSET DRIFT: 3µV/°C max
ꢀ LOW NOISE: 35nV/√Hz
The INA126 and INA2126 are precision instrumentation ampli-
fiers for accurate, low noise differential signal acquisition. Their
two-op-amp design provides excellent performance with very
low quiescent current (175µA/channel). This, combined with a
wide operating voltage range of ±1.35V to ±18V, makes them
ideal for portable instrumentation and data acquisition sys-
tems.
ꢀ LOW INPUT BIAS CURRENT: 25nA max
Gain can be set from 5V/V to 10000V/V with a single
external resistor. Laser trimmed input circuitry provides low
offset voltage (250µV max), low offset voltage drift (3µV/°C
max) and excellent common-mode rejection.

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.
NOTES: (1) Stresses above these ratings may cause permanent damage.
(2) Input signal voltage is limited by internal diodes connected to power
supplies. See text.
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.

equation (1). Low resistor values required for high gain can
make wiring resistance important. Sockets add to the wiring
resistance, which will contribute additional gain error in
gains of approximately 100 or greater.
APPLICATION INFORMATION
Figure 1 shows the basic connections required for operation
of the INA126. Applications with noisy or high impedance
power supplies may require decoupling capacitors close to
the device pins as shown.
OFFSET TRIMMING
The output is referred to the output reference (Ref) terminal
which is normally grounded. This must be a low-impedance
connection to ensure good common-mode rejection. A resis-
tance of 8Ω in series with the Ref pin will cause a typical
device to degrade to approximately 80dB CMR.
The INA126 and INA2126 are laser trimmed for low offset
voltage and offset voltage drift. Most applications require no
external offset adjustment. Figure 2 shows an optional cir-
cuit for trimming the output offset voltage. The voltage
applied to the Ref terminal is added to the output signal. An
op amp buffer is used to provide low impedance at the Ref
terminal to preserve good common-mode rejection.
Dual versions (INA2126) have feedback sense connections,
SenseA and SenseB. These must be connected to their respec-
tive output terminals for proper operation. The sense con-
nection can be used to sense the output voltage directly at the
load for best accuracy.

INPUT BIAS CURRENT RETURN
The internal op amp A2 is identical to A1 and its output
swing is limited to typically 0.7V from the supply rails.
When the input common-mode range is exceeded (A2’s
output is saturated), A1 can still be in linear operation and
respond to changes in the non-inverting input voltage. The
output voltage, however, will be invalid.
The input impedance of the INA126/2126 is extremely
high—approximately 109Ω. However, a path must be pro-
vided for the input bias current of both inputs. This input
bias current is typically –10nA (current flows out of the
input terminals). High input impedance means that this input
bias current changes very little with varying input voltage.
LOW VOLTAGE OPERATION
Input circuitry must provide a path for this input bias current
for proper operation. Figure 3 shows various provisions for
an input bias current path. Without a bias current path, the
inputs will float to a potential which exceeds the common-
mode range and the input amplifiers will saturate.
The INA126/2126 can be operated on power supplies as low
as ±1.35V. Performance remains excellent with power sup-
plies ranging from ±1.35V to ±18V. Most parameters vary
only slightly throughout this supply voltage range—see
typical characteristic curves. Operation at very low supply
voltage requires careful attention to ensure that the common-
mode voltage remains within its linear range. See “Input
Common-Mode Voltage Range.”
If the differential source resistance is low, the bias current
return path can be connected to one input (see the thermo-
couple example in Figure 3). With higher source impedance,
using two equal resistors provides a balanced input with
advantages of lower input offset voltage due to bias current
and better high-frequency common-mode rejection.
The INA126/2126 can be operated from a single power
supply with careful attention to input common-mode range,
output voltage swing of both op amps and the voltage
applied to the Ref terminal. Figure 4 shows a bridge ampli-
fier circuit operated from a single +5V power supply. The
bridge provides an input common-mode voltage near 2.5V,
with a relatively small differential voltage.

INPUT PROTECTION
47kΩ
47kΩ
The inputs are protected with internal diodes connected to
the power supply rails. These diodes will clamp the applied
signal to prevent it from exceeding the power supplies by
more than approximately 0.7V. If the signal source voltage
can exceed the power supplies, the source current should be
limited to less than 10mA. This can generally be done with
a series resistor. Some signal sources are inherently current-
limited and do not require limiting resistors.

CHANNEL CROSSTALK—DUAL VERSION
The two channels of the INA2126 are completely indepen-
dent, including all bias circuitry. At DC and low frequency
there is virtually no signal coupling between channels.
Crosstalk increases with frequency and is dependent on
circuit gain, source impedance and signal characteristics.
INA126
As source impedance increases, careful circuit layout will
help achieve lowest channel crosstalk. Most crosstalk is
produced by capacitive coupling of signals from one channel
to the input section of the other channel. To minimize
coupling, separate the input traces as far as practical from
any signals associated with the opposite channel. A grounded
guard trace surrounding the inputs helps reduce stray cou-
pling between channels. Carefully balance the stray capaci-
tance of each input to ground, and run the differential inputs
of each channel parallel to each other, or directly adjacent on
top and bottom side of a circuit board. Stray coupling then
tends to produce a common-mode signal that is rejected by
the IA’s input.
Center-tap provides
bias current return.
FIGURE 3. Providing an Input Common-Mode Current Path.
INPUT COMMON-MODE RANGE
The input common-mode range of the INA126/2126 is
shown in the typical characteristic curves. The common-
mode range is limited on the negative side by the output
voltage swing of A2, an internal circuit node that cannot be
measured on an external pin. The output voltage of A2 can
be expressed as:
VO2 = 1.25 VI–N – (VI+N – VI–N) (10kΩ/RG)

The ADS7817’s VREF input current is proportional to conversion rate. A
conversion rate of 10kS/s or slower assures enough current to turn on the
reference diode. Converter input range is ±1.2V. Output swing limitation of
INA126 limits the A/D converter to somewhat greater than 11 bits of range.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is provided. TI bases its knowledge and belief on information
provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and
continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
