TLV2721
- Output swing includes both supply rails
- Low noise: 38nV/√Hz (typical) at f = 1kHz
- Low input bias current: 1pA (typical)
- Fully specified for single-supply 3V and 5V operation
- Very low power: 110µA (typical)
- Common-mode input voltage range includes negative rail
- Wide supply voltage range: 2.7V to 10V
The TLV2721 is a single low-voltage operational amplifier available in the SOT-23 package. The TLV2721 offers a compromise between the ac performance and output drive of the TLV2731 and the micropower TLV2711. The device consumes only 150µA (max) of supply current and is an excellent choice for battery-powered applications. The device exhibits rail-to-rail output performance for increased dynamic range in single or split-supply applications.
The TLV2721 is fully characterized at 3V and 5V and is optimized for low-voltage applications. The TLV2721, 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 3V operation, these devices work well in battery operated 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 PCB traces.
