description
The TLV2211 is a single operational amplifier manufactured using the TexasInstrumentsAdvancedLinCMOS
process. These devices are optimized and fully specified for single-supply 3-V and 5-V operation. For this
low-voltage operation combined with micropower dissipation levels, the input noise voltage performance has
been dramatically improved using optimized design techniques for CMOS-type amplifiers. Another added
benefit is that these amplifiers exhibit rail-to-rail output swing. The output dynamic range can be extended using
the TLV2211 with loads referenced midway between the rails. The common-mode input voltage range is wider
than typical standard CMOS-type amplifiers. To take advantage of this improvement in performance and to
make this device available for a wider range of applications, V
voltage test limit of ± 5 mV, allowing a minimum of 0 to 2-V common-mode input voltage range for a 3-V power
is specified with a larger maximum input offset
ICR
supply.

The Advanced LinCMOS process uses a silicon-gate technology to obtain input offset voltage stability with
temperatureandtimethatfarexceedsthatobtainableusingmetal-gatetechnology. Thistechnologyalsomakes
possible input-impedance levels that meet or exceed levels offered by top-gate JFET and expensive
dielectric-isolated devices.
The TLV2211, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for
high-impedance sources such as piezoelectric transducers. Because of the low 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 these devices excellent
choices when interfacing directly to analog-to-digital converters (ADCs). All of these features combined with its
temperature performance make the TLV2211 ideal for remote pressure sensors, temperature control, active
voltage-resistive (VR) sensors, accelerometers, hand-held metering, and many other applications.
