The TLC2252 and TLC2254 are dual and quadruple operaTIonal amplifiers from Texas Instruments. Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applicaTIons. The TLC225x family consumes only 35 uA of supply current per channel. This micropower operaTIon makes them good choices for battery-powered applicaTIons. The noise performance has been dramatically improved over previous generations of CMOS amplifiers. Looking at Figure 1, the TLC225x has a noise level of 19 nV/Hz at 1kHz; four times lower than competitive micropower solutions.
The TLC225x amplifiers, exhibiting high input impedance and low noise, are excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers.
