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.

The TLC226x, 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 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.
