Precision, Low Power, G = 10, 100
INSTRUMENTATION AMPLIFIER
FEATURES
● LOW OFFSET VOLTAGE: 50µV max
● LOW DRIFT: 0.5µV/°C max
DESCRIPTION
The INA141 is a low power, general purpose instru-
mentation 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).
● ACCURATE GAIN: ±0.05% at G = 10
● LOW INPUT BIAS CURRENT: 5nA max
● HIGH CMR: 117dB min
● INPUTS PROTECTED TO ±40V
● WIDE SUPPLY RANGE: ±2.25 to ±18V
● LOW QUIESCENT CURRENT: 750µA
● 8-PIN PLASTIC DIP, SO-8
Simple pin connections set an accurate gain of 10 or
100V/V without external resistors. Internal input pro-
tection can withstand up to ±40V without damage.
The INA141 is laser trimmed for very low offset
voltage (50µV), drift (0.5µV/°C) and high common-
mode rejection (117dB at G = 100). It operates with
power supplies as low as ±2.25V, and quiescent
current is only 750µA—ideal for battery operated
systems.
APPLICATIONS
● BRIDGE AMPLIFIER
● THERMOCOUPLE AMPLIFIER
● RTD SENSOR AMPLIFIER
● MEDICAL INSTRUMENTATION
● DATA ACQUISITION
The INA141 is available in 8-pin plastic DIP, and
SO-8 surface-mount packages, specified for the –40°C
to +85°C temperature range.

INA141
APPLICATION INFORMATION
Gains between 10 and 100 can be achieved by connecting an
external resistor to the jumper pins. This is not recom-
mended, however, because the ±25% variation of internal
resistor values makes the required external resistor value
uncertain. A companion model, INA128, features accurately
trimmed internal resistors so that gains from 1 to 10,000 can
be set with an external resistor.
Figure 1 shows the basic connections required for operation
of the INA141. Applications with noisy or high impedance
power supplies may require decoupling capacitors close to
the device pins as shown.
The output is referred to the output reference (Ref) terminal
which is normally grounded. This must be a low-impedance
connection to assure 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 (G = 1).
DYNAMIC PERFORMANCE
The typical performance curve “Gain vs Frequency” shows
that, despite its low quiescent current, the INA141 achieves
wide bandwidth, even at G = 100. This is due to the current-
feedback topology of the INA141. Settling time also re-
mains excellent at G = 100.
SETTING THE GAIN
Gain is 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 INA141 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 chopper-
stabilized amplifiers.
Internal resistor ratios are laser trimmed to assure excellent
gain accuracy. Actual resistor values can vary by approxi-
mately ±25% from the nominal values shown.

OFFSET TRIMMING
Microphone,
Hydrophone
etc.
The INA141 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 3. Providing an Input Common-Mode Current Path.
FIGURE 2. Optional Trimming of Output Offset 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 INA141 will be near 0V even
though both inputs are overloaded.
INPUT BIAS CURRENT RETURN PATH
The input impedance of the INA141 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.
LOW VOLTAGE OPERATION
The INA141 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 through 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 require-
ments of internal nodes limit the input common-mode range
with low power supply voltage. Typical performance curves,
“Input Common-Mode Range vs Output Voltage” show the
range of linear operation for ±15V, ±5, and ±2.5V supplies.
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 of the INA141 and the input amplifiers will
saturate.
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
possible advantages of lower input offset voltage due to bias
current and better high-frequency common-mode rejection.
INPUT PROTECTION
The inputs of the INA141 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 approxi-
mately 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.
INPUT COMMON-MODE RANGE
The linear input voltage range of the input circuitry of the
INA141 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 to in-
crease, however, the linear input range will be limited by the
output voltage swing of amplifiers A1 and A2. So the linear
common-mode input range is related to the output voltage of
the complete amplifier. This behavior also depends on sup-
ply voltage—see performance curves “Input Common-Mode
Range vs Output Voltage”.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability 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.
