description
The TLV2252 and TLV2254 are dual and
quadruple low-voltage operational amplifiers from
Texas Instruments. Both devices exhibit rail-to-rail
output performance for increased dynamic range
in single- or split-supply applications. The
TLV225x family consumes only 34
μ
A of supply
current per channel. This micropower operation
makes them good choices for battery-powered
applications. This family is fully characterized at
3 V and 5 V and is optimized for low-voltage
applications. The noise performance has been
dramatically improved over previous generations
of CMOS amplifiers. The TLV225x has a noise
level of 19 nV/
√
Hz at 1kHz, four times lower than
competitive micropower solutions.
The TLV225x, exhibiting high input impedance
and low noise, are excellent for small-signal
conditioning for high-impedance sources, such as
piezoelectric transducers. Because of the micro-
power dissipation levels combined with 3-V
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 TLV225xA family is
available and has a maximum input offset voltage of 850
μ
V.
The TLV2252/4 also make great upgrades to the TLV2322/4 in standard designs. They offer increased output
dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set allows them to
be used in a wider range of applications. For applications that require higher output drive and wider input voltage
range, see the TLV2432 and TLV2442 devices. If your design requires single amplifiers, please see the
TLV2211/21/31 family. These devices are single rail-to-rail operational amplifiers in the SOT-23 package. Their
small size and low power consumption, make them ideal for high density, battery-powered equipment.
