HIGH-LEVEL OUTPUT CURRENT
The TLV2422 and TLV2422Aare 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-voltageoperation. TheTLV2422onlyrequires
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.

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.
