The TLV2221 is a single low-voltage
operational amplifier available in the SOT-23 package. TLV2221 offers a compromise
between the ac performance and output drive of the TLV2231 and the micro-power TLV2211.
TLV2221 consumes only 150µA (max) of
supply current and is designed for battery-powered applications. The device exhibits
rail-to-rail output performance for increased dynamic range in single- or
split-supply 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
micro-power dissipation levels combined with 3V 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).
With a total area of 5.6mm2, the SOT-23 package only
requires one-third the board space of the standard 8-pin SOIC package. This
ultra-small package allows designers to place single amplifiers very close to the
signal source, minimizing noise pick-up from long printed circuit board (PCB)
traces. TI has also taken special care to provide a pinout that is optimized for
board layout (see Typical Surface-Mount Layout for a Fixed-Gain Non-inverting
Amplifier). Both inputs are separated by GND to prevent coupling or leakage paths. The OUT
and IN− terminals are on the same end of the board to provide negative feedback.
Finally, gain setting resistors and decoupling capacitor are easily placed around
the package.
