TI精密运算放大器TLV2464是具有高输出驱动能力，且具有【轨到轨】高性能输出的低电源工作、带关断功能的四运算精密放大器。这种轨到轨的动态范围和高输出驱动连接使得TLV2464常常作为模数转换器的缓冲。需要注意TLV2464要求低电源，正负电源电压差不能超过6V。其引脚如图1所示。
该TLV246x是一种低功耗rail-to-rail 系列输入/输出运算放大器，专门为军工级、高要求工业级便携式工作应用设计之运算极品芯片.
除了高密度电路外.规定工作温度范围扩大 (T A = – 40°C到125°C)为
使用在工业控制和汽车系统，并达到在军用温度范围 (TA = – 55°C以125°C)在军事系统中使
