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 applications.

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.
