FEATURES
DESCRIPTION
● LOW OFFSET VOLTAGE: 50µV max
● LOW DRIFT: 0.5µV/°C max
The INA2141 is a low power, dual instrumentation
amplifier offering excellent accuracy. Its versatile
3-op amp design and small size make it ideal for a
wide range of applications. Current-feedback input
circuitry provides wide bandwidth even at high gain
(200kHz at G = 100).
● EXCELLENT GAIN ACCURACY:
±0.05% max at G = 10
● LOW INPUT BIAS CURRENT: 5nA max
● HIGH CMR: 117dB min (G = 100)
● INPUTS PROTECTED TO ±40V
Simple pin connections set an accurate gain of 10 or
100V/V without external resistors. Internal input protection can withstand up to ±40V without damage.
● WIDE SUPPLY RANGE: ±2.25V to ±18V
● LOW QUIESCENT CURRENT: 750µA/IA
The INA2141 is laser trimmed for very low offset
voltage (50µV), drift (0.5µV/°C) and high commonmode rejection (117dB at G = 100). It operates with
power supplies as low as ±2.25V, and quiescent current is only 750µA per amplifier—ideal for battery
operated systems.

This integrated circuit can be damaged by ESD. Burr-Brown
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.

INA2141
APPLICATION INFORMATION
Internal resistor ratios are laser trimmed to assure excellent
gain accuracy. Actual resistor values can vary by approximately ±25% from the nominal values shown.
Figure 1 shows the basic connections required for operation
of the INA2141. Applications with noisy or high impedance
power supplies may require decoupling capacitors close to
the device pins as shown.
Gains between 10 and 100 can be achieved by connecting an
external resistor to the jumper pins. This is not recommended, however, because the ±25% variation of internal
resistor values makes the required external resistor value
uncertain. A companion model, INA2128, features accurately trimmed internal resistors so that gains from 1 to
10,000 can be set with an external resistor.
The output is referred to the output reference (Ref) terminals
(RefA and RefB) which are normally grounded. These must
be low-impedance connections to assure good commonmode rejection. A resistance of 8Ω in series with a Ref pin
will cause a typical device to degrade to approximately
80dB CMR (G = 1).
The INA2141 has a separate output sense feedback connections SenseA and SenseB. These must be connected to their
respective output terminals for proper operation. The output
sense connection can be used to sense the output voltage
directly at the load for best accuracy.
DYNAMIC PERFORMANCE
The typical performance curve “Gain vs Frequency” shows
that despite its low quiescent current, the INA2141 achieves
wide bandwidth, even at high gain. This is due to its currentfeedback topology. Settling time also remains excellent at
high gain.
SETTING THE GAIN
Gain of each IA can be independently selected with a jumper
connection as shown in Figure 1. G = 10V/V with no jumper
installed. With a jumper installed G = 100V/V. To preserve
good gain accuracy, this jumper must have low series
resistance. A resistance of 0.5Ω in series with the jumper
will decrease the gain by 0.1%.
NOISE PERFORMANCE
The INA2141 provides very low noise in most applications.
Low frequency noise is approximately 0.2µVp-p measured
from 0.1 to 10Hz (G = 100). This provides dramatically
improved noise when compared to state-of-the-art chopperstabilized amplifiers.

OFFSET TRIMMING
The INA2141 is laser trimmed for low offset voltage and
offset voltage drift. Most applications require no external
offset adjustment. Figure 2 shows an optional circuit for
trimming the output offset voltage. The voltage applied to
Ref terminal is summed with the output. The op amp buffer
provides low impedance at the Ref terminal to preserve good
common-mode rejection.

FIGURE 2. Optional Trimming of Output Offset Voltage.
FIGURE 3. Providing an Input Common-Mode Current Path.
INPUT BIAS CURRENT RETURN PATH
The input impedance of the INA2141 is extremely high—
approximately 1010Ω. However, a path must be provided for
the input bias current of both inputs. This input bias current
is approximately ±2nA. High input impedance means that
this input bias current changes very little with varying input
voltage.
mon-mode input range is related to the output voltage of the
complete amplifier. This behavior also depends on supply
voltage—see performance curves “Input Common-Mode
Range vs Output Voltage”.
Input-overload can produce an output voltage that appears
normal. For example, if an input overload condition drives
both input amplifiers to their positive output swing limit, the
difference voltage measured by the output amplifier will be
near zero. The output of the INA2141 will be near 0V even
though both inputs are overloaded.
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 commonmode range of the INA2141 and the input amplifiers will
saturate.
LOW VOLTAGE OPERATION
The INA2141 can be operated on power supplies as low as
±2.25V. Performance remains excellent with power supplies ranging from ±2.25V to ±18V. Most parameters vary
only slightly throughout this supply voltage range—see
typical performance curves. Operation at very low supply
voltage requires careful attention to assure that the input
voltages remain within their linear range. Voltage swing
requirements of internal nodes limit the input commonmode range with low power supply voltage. Typical performance curves, “Input Common-Mode Range vs Output
Voltage” show the range of linear operation for ±15V, ±5V,
and ±2.5V supplies.
If the differential source resistance is low, the bias current
return path can be connected to one input (see the thermocouple example in Figure 3). With higher source impedance,
using two equal resistors provides a balanced input with
possible advantages of lower input offset voltage due to bias
current and better high-frequency common-mode rejection.
INPUT COMMON-MODE RANGE
The linear input voltage range of the input circuitry of the
INA2141 is from approximately 1.4V below the positive
supply voltage to 1.7V above the negative supply. As a
differential input voltage causes the output voltage increase,
however, the linear input range will be limited by the output
voltage swing of amplifiers A1 and A2. So the linear com-

INPUT PROTECTION
The inputs of the INA2141 are individually protected for
voltages up to ±40V. For example, a condition of –40V on
one input and +40V on the other input will not cause
damage. Internal circuitry on each input provides low series
impedance under normal signal conditions. To provide
equivalent protection, series input resistors would contribute
excessive noise. If the input is overloaded, the protection
circuitry limits the input current to a safe value of approximately 1.5 to 5mA. The typical performance curve “Input
Bias Current vs Common-Mode Input Voltage” shows this
input current limit behavior. The inputs are protected even if
the power supplies are disconnected or turned off.
there is virtually no signal coupling between channels.
Crosstalk increases with frequency and is dependent on
circuit gain, source impedance and signal characteristics.
As source impedance increases, careful circuit layout will
help achieve lowest channel crosstalk. Most crossstalk 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 coupling between channels. 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 which is rejected by the
IA’s input.
