description
The TLV2221 is a single low-
voltage operational amplifier available in the SOT-23 package. It offers a compromise between the ac performance and output drive of the TLV2231 and the micropower TLV2211.
It consumes only 150 µA (max) of supply current and is ideal for battery-powered applications. The device exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLV2221 is fully characterized at 3 V and 5 V and is optimized for low-
voltage applications.
The TLV2221, exhibiting high input impedance and low noise, is excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. Because of the micropower 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 this family a great choi...
