TLC2254QDG4

高级LinCMOS轨到轨极低功耗运算放大器 Advanced LinCMOS RAIL-TO-RAIL VERY LOW-POWER OPERATIONAL AMPLIFIERS

description

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 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 TLC225x has a noise level of 19 nV/√Hzat 1kHz; four times lower than competitive micropower solutions.
