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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VDD+ and VDD – .
2. Differential voltages are at IN+ with respect to IN –. Excessive current flows if input is brought below VDD – – 0.3 V.
3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded.
