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-

Ω 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

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.
