description

The TLV2422 and TLV2422A are dual low-voltage

operational amplifiers from Texas Instruments.

The common-mode input voltage range for this

device has been extended over the typical CMOS

amplifiers making them suitable for a wide range

of applications. In addition, the 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 TLV2422 only requires 50 μA of supply

current per channel, making it ideal for battery-powered applications. The TLV2422 also has increased output

drive over previous rail-to-rail operational amplifiers and can drive 600-Ω loads for telecom applications.

Other members in the TLV2422 family are the high-power, TLV2442, and low-power, TLV2432, versions.

The TLV2422, 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 TLV2422A 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.
