description
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 single- or 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-
loads for telecommunications
applications.
The other members in the TLV244x family are the low-power, TLV243x, and micro-power, TLV2422, 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
V.
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.
NOTES:
1. All voltage values, except differential voltages, are with respect to the midpoint between VDD+ and VDD .
2. Differential voltages are at IN+ with respect to IN . Excessive current will flow if input is brought below VDD 0.3 V.
3. 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.
