FEATURES
DESCRIPTION
The LME49723 is part of the ultra-low distortion, low
noise, high slew rate operational amplifier series
optimized and fully specified for high performance,
high fidelity applications. Combining advanced
leading-edge process technology with state-of-the-art
circuit design, the LME49723 audio operational
amplifiers deliver superior audio signal amplification
for outstanding audio performance. The LME49723
combines extremely low voltage noise density
(3.6nV/√Hz) with vanishingly low THD+N (0.0002%)
to easily satisfy the most demanding audio
applications. To ensure that the most challenging
loads are driven without compromise, the LME49723
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 LME49723's outstanding CMRR (100dB), PSRR
(100dB), and VOS (0.3mV) give the amplifier excellent
operational amplifier DC performance.
The LME49723 has a wide supply range of ±2.5V to
±17V. Over this supply range the LME49723’s input
circuitry maintains excellent common-mode and
power supply rejection, as well as maintaining its low
input bias current. The LME49723 is unity gain
stable.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
(2) Operating Ratings indicate conditions for which the device is functional, but do not ensure specific performance limits. For ensured
specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed.
Some performance characteristics may degrade when the device is not operated under the listed test conditions.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) Amplifier output connected to GND, any number of amplifiers within a package.
(5) Human body model, 100pF discharged through a 1.5kΩ resistor.
(6) Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage and then
discharged directly into the IC with no external series resistor (resistance of discharge path must be under 50Ω).

APPLICATION INFORMATION
DISTORTION MEASUREMENTS
The vanishingly low residual distortion produced by LME49723 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 LME49723’s low residual distortion is an input referred internal error. As shown in Figure 47, 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 closed-loop
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 47.
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 LME49723 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.

(1) 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.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
