description
The TLC2262 and TLC2264 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
TLC226x family offers a compromise between the
micropower TLC225x and the ac performance of
the TLC227x. It has low supply current for
battery-powered applications, while still having
adequate ac performance for applications that
demand it. The noise performance has been
dramatically improved over previous generations
of CMOS amplifiers. Figure 1 depicts the low level
of noise voltage for this CMOS amplifier, which
has only 200 µA (typ) of supply current per
amplifier.

conditioning for high-impedance sources, such as

piezoelectric transducers. Because of the micro-
power dissipation levels, these devices work well
Figure 1
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 TLC226xA
family is available and has a maximum input offset voltage of 950 µV. This family is fully characterized at 5 V
and ± 5 V.
The TLC2262/4 also makes great upgrades to the TLC27M2/L4 or TS27M2/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 range, see the TLV2432 and TLV2442. 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.
