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-

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.
