description
The TLC2252 and TLC2254 are dual and
quadruple operational amplifiers from Texas
Instruments. Both devices exhibit rail-to-rail
output performance for increased dynamic range
in single- or split-supply applications. The
TLC225x family consumes only 35
μ
A of supply
current per channel. This micropower operation
makes them good choices for battery-powered
applications. The noise performance has been
dramatically improved over previous generations
of CMOS amplifiers. Looking at Figure 1, the
TLC225x has a noise level of 19 nV/
√
Hz at 1kHz;
four times lower than competitive micropower
solutions.
The TLC225x amplifiers, exhibiting high input
impedance and low noise, are excellent for
small-signal conditioning for high-impedance
sources, such as piezoelectric transducers.
Because of the micropower dissipation levels,
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 TLC225xA family is available and has a maximum input offset voltage of 850
μ
V. This
family is fully characterized at 5 V and
±
5 V.
The TLC2252/4 also makes great upgrades to the TLC27L2/L4 or TS27L2/L4 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 ranges, see the TLV2432 and TLV2442 devices. If the 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.
