description
The TLV243x and TLV243xA are low-voltage
operational amplifier from Texas Instruments. The
common-mode input voltage range for each
device is extended over the typical 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. The TLV243x only requires 100 µA
(typ) of supply current per channel, making it ideal
for battery-powered applications. The TLV243x
also has increased output drive over previous
rail-to-rail operational amplifiers and can drive
600-Ω loads for telecom applications.

The other members in the TLV243x family are the high-power, TLV244x, and micro-power, TLV2422, versions.
The TLV243x, 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 TLV243xA is available and
has 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.
