DESCRIPTION
The differential amplifier is the foundation of many
commonly used circuits. The low cost INA143 and
INA2143 provide this precision circuit function without
using an expensive precision network.
The INA143 and INA2143 are high slew rate, gain of
10V/V or 0.1V/V difference amplifiers consisting of a
precision op amp with a precision resistor network. The
on-chip resistors are laser trimmed for accurate gain and
high common-mode rejection. Excellent TCR tracking
of the resistor maintains gain accuracy and commonmode rejection over temperature. They operate over a
wide supply range, ±2.25V to ±18V (+4.5V to +36V
single supply), and input common-mode voltage range
extends beyond the positive and negative supply rails.
The single version, INA143, package is the SO-8 surface
mount. The dual version, INA2143, package is the SO-14
surface mount. Both are specified for operation over the
extended industrial temperature range, –40°C to +85°C.
Operation is from –55°C to +125°C.

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.
NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability. (2) One channel per package.

APPLICATIONS INFORMATION
throughout the full operating voltage range. Parameters which
vary significantly with operating voltage are shown in the
Typical Performance Curves.
The INA143 and INA2143 are high-speed difference amplifiers suitable for a wide range of general-purpose applications. Figure 1 shows the basic G = 10 configuration. The
input and feedback resistors can be reversed to achieve
G = 0.1, as shown in Figure 2. For applications requiring
G = 1, the INA133 and INA2133 are recommended.
OFFSET VOLTAGE TRIM
The INA143 and INA2143 are laser trimmed for low offset
voltage and drift. Most applications require no external offset
adjustment. Figure 3 shows an optional circuit for trimming
the output offset voltage. The output is referred to the output
reference terminal (pin 1), which is normally grounded. A
voltage applied to the Ref terminal will be summed with the
output signal. This can be used to null offset voltage as
shown in Figure 3. The source impedance of a signal applied
to the Ref terminal should be less than 10Ω to maintain good
common-mode rejection.
Decoupling capacitors are strongly recommended for applications with noisy or high impedance power supplies. The
capacitors should be placed close to the device pins as
shown in Figure 1. All circuitry is completely independent
in the dual version assuring lowest crosstalk and normal
behavior when one amplifier is overdriven or short-circuited.
As shown in Figure 1, the differential input signal is connected to pins 2 and 3. The source impedances connected to
the inputs must be nearly equal to assure good commonmode rejection. A 5Ω mismatch in source impedance will
degrade the common-mode rejection of a typical device to
approximately 86dB (RTI). If the source has a known
impedance mismatch, an additional resistor in series with
the opposite input can be used to preserve good commonmode rejection.

The INA143’s internal resistors are accurately ratio trimmed
to match. That is, R1/R2 and R3/R4 are trimmed to equal 0.1.
However, the absolute values may not be equal (R1 + R2 may
be slightly different than R3 + R4). Thus, large series resistors
on the input (greater than 100Ω), even if well matched, will
degrade common-mode rejection.

The INA143 and INA2143 operate from single (+4.5V to

performance. Specifications are production tested with ±5V

This circuit follows an 11/1 divider with a gain of 11 for an overall gain of unity.
With an 11/1 divider, the input signal can exceed 55V without damage as
long as input current is less than 0.5mA.

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 - 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.

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,

express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
