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 applica-
tions. 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
μ
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.
