资 源 简 介
The TLV2252 and TLV2254 are dual and quadruple low-voltage operaTIonal amplifiers from Texas Instruments. Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applicaTIons. The TLV225x family consumes only 34 µA of supply current per channel. This micropower operaTIon makes them good choices for battery-powered applicaTIons. This family is fully characterized at 3 V and 5 V and is optimized for low-voltage applications. The noise performance has been dramatically improved over previous generations of CMOS amplifiers. The TLV225x has a noise level of 19 nV/Hz at 1kHz, four times lower than competitive micropower solutions.
The TLV225x, exhibiting high input impedance and low noise, are excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers.
