TLC2254IDR

Product Summary

The TLC2254IDR is a dual and quadruple operational amplifier from Texas Instruments. Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLC2254IDR family consumes only 35 μA 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 TLC2254IDR has a noise level of 19 nV/√Hz at 1kHz; four times lower than competitive micropower solutions. The TLC2254IDR amplifiers, exhibiting high input impedance and low noise, are excellent for small-signal conditioning for high-impedance sources, such as piezoelectric transducers. Because of the micropower dissipation levels, 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). For precision applications, the TLC2254IDR family is available and has a maximum input offset voltage of 850 μV. This family is fully characterized at 5 V and ±5 V.
