DESCRIPTION

6

The INA137 and INA2137 are differential line receivers
consisting of high performance op amps with on-chip
precision resistors. They are fully specified for high
performance audio applications and have excellent ac
specifications, including low distortion (0.0005% at
1kHz) and high slew rate (14V/µs), assuring good
dynamic response. In addition, wide output voltage

swing and high output drive capability allow use in a
wide variety of demanding applications. The dual ver­sion features completely independent circuitry for low­est crosstalk and freedom from interaction, even when
overdriven or overloaded.

The INA137 and INA2137 on-chip resistors are laser
trimmed for accurate gain and optimum
common-mode rejection. Furthermore, excellent TCR
tracking of the resistors maintains gain accuracy and
common-mode rejection over temperature. Operation
is guaranteed from ±4V to ±18V (8V to 36V total
supply).

The INA137 is available in 8-pin DIP and SO-8
surface-mount packages. The INA2137 comes in
14-pin DIP and SO-14 surface-mount packages. Both
are specified for operation over the extended industrial
temperature range, –40°C to +85°C.

DISCHARGE SENSITIVITY

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.

APPLICATIONS INFORMATION

The INA137 and INA2137 are differential line receivers
suitable for a wide range of audio and general-purpose
applications. Figure 1 shows the basic G = 1/2 (–6dB)
differential receiver configuration. The input and feedback
resistors can be reversed to achieve G = 2 (+6dB), as shown
in Figure 2. For applications requiring G = 1 (0dB), the
INA134 and INA2134 are recommended.

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 77dB (RTO). 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 INA137 and INA2137 have excellent distortion charac­teristics. THD+Noise is below 0.001% throughout the audio
frequency range. Up to approximately 10kHz distortion is
below the measurement limit of commonly used test equip­ment. Furthermore, distortion remains relatively flat over its
wide output voltage swing range (approximately 1.7V from
either supply).

OFFSET VOLTAGE TRIM

The INA137 and INA2137 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.

AUDIO PERFORMANCE

The INA137 and INA2137 were designed for enhanced ac
performance. Very low distortion, low noise, and wide band­width provide superior performance in high quality audio
applications. Laser-trimmed matched resistors provide opti­mum common-mode rejection (typically 90dB), especially
when compared to circuits implemented with an op amp
and discrete precision resistors. In addition, high slew rate
(14V/µs) and fast settling time (3µs to 0.01%) ensure excel­lent dynamic performance.

IMPORTANT NOTICE

Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
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,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
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
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
