HIGH-LEVEL OUTPUT CURRENT
The TLV2262 and TLV2264 are dual and quad low
voltage operational amplifiers from Texas Instru-
ments. Both devices exhibit rail-to-rail output
performance for increased dynamic range in
single or split supply applications. The TLV226x
family offers a compromise between the micro-
power TLV225x 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.
This family is fully characterized at 3 V and 5 V and
is optimized for low-voltage applications. The
noise performance has been dramatically im-
proved 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 TLV226x, 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-

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 TLV226xA family is available and has a
maximum input offset voltage of 950 µV.
The TLV2262/4 also makes great upgrades to the TLV2332/4 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.
