DESCRIPTION
The INA103 is a very low noise, low distortion monolithic instrumentation amplifier. Its current-feedback
circuitry achieves very wide bandwidth and excellent
dynamic response. It is ideal for low-level audio
signals such as balanced low-impedance microphones.
The INA103 provides near-theoretical limit noise performance for 200Ω source impedances. Many industrial applications also benefit from its low noise and
wide bandwidth.
The INA103 is available in 16-pin plastic DIP and
SOL-16 surface-mount packages. Commercial and Industrial temperature range models are available.
Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain. Its
balanced input, low noise and low distortion provide
superior performance compared to transformer-coupled
microphone amplifiers used in professional audio
equipment.
The INA103’s wide supply voltage (±9 to ±25V) and
high output current drive allow its use in high-level
audio stages as well. A copper lead frame in the plastic
DIP assures excellent thermal performance.

Any 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
published specifications.

APPLICATIONS INFORMATION
useful if various input sources are connected to the INA103.
Although not shown in other figures, this network can be
used, if needed, with all applications shown.
Figure 1 shows the basic connections required for operation.
Power supplies should be bypassed with 1µF tantalum
capacitors near the device pins. The output Sense (pin 11)
and output Reference (pin 7) should be low impedance
connections. Resistance of a few ohms in series with these
connections will degrade the common-mode rejection of the
amplifier.
To avoid oscillations, make short, direct connection to the
gain set resistor and gain sense connections. Avoid running
output signals near these sensitive input nodes.
GAIN SELECTION
Gains of 1 or 100V/V can be set without external resistors.
For G = 1V/V (unity gain) leave pin 14 open (no connection)—see Figure 4. For G = 100V/V, connect pin 14 to pin
6—see Figure 5.
Gain can also be accurately set with a single external resistor
as shown in Figure 1. The two internal feedback resistors are
laser-trimmed to 3kΩ within approximately ±0.1%. The
temperature coefficient of these resistors is approximately
50ppm/˚C. Gain using an external RG resistor is—
6kΩ

RG
INPUT CONSIDERATIONS
Certain source impedances can cause the INA103 to oscillate. This depends on circuit layout and source or cable
characteristics connected to the input. An input network
consisting of a small inductor and resistor (Figure 2) can
greatly reduce the tendancy to oscillate. This is especially

FIGURE 2. Input Stabilization Network.
Offset voltage can be trimmed with the optional circuit
shown in Figure 3. This offset trim circuit primarily adjusts
the output stage offset, but also has a small effect on input
stage offset. For a 1mV adjustment of the output voltage, the
input stage offset is adjusted approximately 1µV. Use this
adjustment to null the INA103’s offset voltage with zero
differential input voltage. Do not use this adjustment to null
offset produced by a sensor, or offset produced by subsequent stages, since this will increase temperature drift.
FIGURE 1. Basic Circuit Configuration.
Accuracy and TCR of the external RG will also contribute to
gain error and temperature drift. These effects can be directly inferred from the gain equation.
Connections available on A1 and A2 allow external resistors
to be substituted for the internal 3kΩ feedback resistors. A
precision resistor network can be used for very accurate and
stable gains. To preserve the low noise of the INA103, the
value of external feedback resistors should be kept low.
Increasing the feedback resistors to 20kΩ would increase
noise of the INA103 to approximately 1.5nV/√Hz. Due to
the current-feedback input circuitry, bandwidth would also
be reduced.
To offset the output voltage without affecting drift, use the
circuit shown in Figure 4. The voltage applied to pin 7 is
summed at the output. The op amp connected as a buffer
provides a low impedance at pin 7 to assure good commonmode rejection.
Figure 5 shows a method to trim offset voltage in ACcoupled applications. A nearly constant and equal input bias
current of approximately 2.5µA flows into both input terminals. A variable input trim voltage is created by adjusting the
balance of the two input bias return resistances through
which the input bias currents must flow.
NOISE PERFORMANCE
The INA103 provides very low noise with low source
impedance. Its 1nV/√Hz voltage noise delivers near theoretical noise performance with a source impedance of 200Ω.
Relatively high input stage current is used to achieve this
low noise. This results in relatively high input bias current
and input current noise. As a result, the INA103 may not
provide best noise performance with source impedances
greater than 10kΩ. For source impedance greater than 10kΩ,
consider the INA114 (excellent for precise DC applications), or the INA111 FET-input IA for high speed applications.

OFFSET ADJUSTMENT
Offset voltage of the INA103 has two components: input
stage offset voltage is produced by A1 and A2; and, output
stage offset is produced by A3. Both input and output stage
offset are laser trimmed and may not need adjustment in
many applications.

OUTPUT SENSE
An output sense terminal allows greater gain accuracy in
driving the load. By connecting the sense connection at the
load, I•R voltage loss to the load is included inside the
feedback loop. Current drive can be increased by connecting a current booster inside the feedback loop as shown in
Figure 11.
Figure 6 shows an active control loop that adjusts the output
offset voltage to zero. A2, R, and C form an integrator that
produces an offsetting voltage applied to one input of the
INA103. This produces a –6dB/octave low frequency rolloff like the capacitor input coupling in Figure 5.
COMMON-MODE INPUT RANGE
For proper operation, the combined differential input signal
and common-mode input voltage must not cause the input
amplifiers to exceed their output swing limits. The linear
input range is shown in the typical performance curve
“Maximum Common-Mode Voltage vs Output Voltage.”
For a given total gain, the input common-mode range can be
increased by reducing the input stage gain and increasing the
output stage gain with the circuit shown in Figure 7.

A common problem with many IC op amps and instrumentation amplifiers is shown in (a). Here, the amplifier’s input is driven beyond its linear common-mode
range, forcing the output of the amplifier into the supply rails. The output then “folds back”, i.e., a more positive input voltage now causes the output of the amplifier
to go negative. The INA103 has protection circuitry to prevent fold-back, and as shown in (b), limits cleanly.

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)

and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
