The Introduction Of TLV2211CDBVR With High Output Current (10 MA)

TLV2211CDBVR  Single, 10-V, 65-kHz operational amplifier with high output current (10 mA)

The TLV2211 is a single low-voltage operational amplifier available in the SOT-23 package. It consumes only 11 µA (typ) of supply current and is ideal for battery-power applications. The TLV2211 has a 3-V noise level of 22 nV/Hz at 1kHz; 5 times lower than competitive SOT-23 micropower solutions. The device exhibits rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLV2211 is fully characterized at 3 V and 5 V and is optimized for low-voltage applications.

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 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 choice when interfacing with analog-to-digital converters (ADCs).

Description For The TLV2211The TLV2211 is a single low-voltage operational amplifier available in the SOT-23 package.

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 PCB traces. TI has also taken special care to provide a pinout that is optimized for board layout. 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.
