DESCRIPTION (CONTINUED)
To ensure that the most challenging loads are driven without compromise, the LME49720 has a high slew rate of
±20V/μs and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that
drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω loads.
The LME49720's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent
operational amplifier DC performance.
The LME49720 has a wide supply range of ±2.5V to ±17V. Over this supply range the LME49720’s input circuitry
maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current.
The LME49720 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while
driving complex loads with values as high as 100pF.
The LME49720 is available in 8–lead narrow body SOIC, 8–lead PDIP, and 8–lead TO-99. Demonstration
boards are available for each package.

APPLICATION INFORMATION
DISTORTION MEASUREMENTS
The vanishingly low residual distortion produced by LME49720 is below the capabilities of all commercially
available equipment. This makes distortion measurements just slightly more difficult than simply connecting a
distortion meter to the amplifier’s inputs and outputs. The solution, however, is quite simple: an additional
resistor. Adding this resistor extends the resolution of the distortion measurement equipment.
The LME49720’s low residual distortion is an input referred internal error. As shown in Figure 110, adding the
10Ω resistor connected between the amplifier’s inverting and non-inverting inputs changes the amplifier’s noise
gain. The result is that the error signal (distortion) is amplified by a factor of 101. Although the amplifier’s closedloop gain is unaltered, the feedback available to correct distortion errors is reduced by 101, which means that
measurement resolution increases by 101. To ensure minimum effects on distortion measurements, keep the
value of R1 low as shown in Figure 110.
This technique is verified by duplicating the measurements with high closed loop gain and/or making the
measurements at high frequencies. Doing so produces distortion components that are within the measurement
equipment’s capabilities. This datasheet’s THD+N and IMD values were generated using the above described
circuit connected to an Audio Precision System Two Cascade.

The LME49720 is a high speed op amp with excellent phase margin and stability. Capacitive loads up to 100pF
will cause little change in the phase characteristics of the amplifiers and are therefore allowable.
Capacitive loads greater than 100pF must be isolated from the output. The most straightforward way to do this is
to put a resistor in series with the output. This resistor will also prevent excess power dissipation if the output is
accidentally shorted.

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)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
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
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
