DESCRIPTION

VDD = 3 V
VOH − High-Level Output Voltage − V
The TLV244x and TLV244xA are low-voltage
operational amplifiers from Texas Instruments. The
common-mode input voltage range of these devices
has been extended over typical standard CMOS
amplifiers, making them suitable for a wide range of
applications. In addition, these devices do not phase
invert when the common-mode input is driven to the
supply rails. This satisfies most design requirements
without paying a premium for rail-to-rail input
performance. They also exhibit rail-to-rail output
performance for increased dynamic range in singleor split-supply applications. This family is fully
characterized at 3-V and 5-V supplies and is
optimized for low-voltage operation. Both devices
offer comparable ac performance while having lower
noise, input offset voltage, and power dissipation than
existing CMOS operational amplifiers. The TLV244x
has increased output drive over previous rail-to-rail
operational amplifiers and can drive 600-Ω loads for
telecommunications applications.

versions.
The TLV244x, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for
high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels and
low-voltage operation, these devices work well in hand-held monitoring and remote-sensing applications. In
addition, the rail-to-rail output feature with single- or split-supplies makes this family a great choice when
interfacing with analog-to-digital converters (ADCs). For precision applications, the TLV244xA is available with a
maximum input offset voltage of 950 µV.
If the design requires single operational amplifiers, see the TI TLV2211/21/31. This is a family of rail-to-rail output
operational amplifiers in the SOT-23 package. Their small size and low power consumption make them ideal for
high-density battery-powered equipment.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values, except differential voltages, are with respect to the midpoint between VDD+ and VDD–.
Differential voltages are at IN+ with respect to IN–. Excessive current will flow if input is brought below VDD– – 0.3 V.
The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum dissipation
rating is not exceeded.

APPLICATION INFORMATION
macromodel information
Macromodel information provided was derived using PSpice™ Parts™ model generation software. The Boyle
macromodel (2) and subcircuit in Figure 51 were generated using the TLV244x typical electrical and operating
characteristics at TA = 25°C. Using this information, output simulations of the following key parameters can be
generated to a tolerance of 20% (in most cases):

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
