高级LinCMOSE轨到轨极低功耗运算放大器 Advanced LinCMOSE RAIL-TO-RAIL VERY LOW-POWER OPERATIONAL AMPLIFIERS
description
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/√Hzat 1kHz, four times lower than competitive micropower solutions.
