LMV981 具有轨至轨输入和输出及关断状态的单路 1.8V 运算放大器

The LMV981 and LMV982 devices are low-voltage, low-power operational amplifiers that are well suited for today’s low-voltage and/or portable applications. Specified for operation of 1.8 V to 5 V, they can be used in portable applications that are powered from a single-cell Li-ion or two-cell batteries. They have rail-to-rail input and output capability for maximum signal swings in low-voltage applications. The LMV98x input common-mode voltage extends 200 mV beyond the rails for increased flexibility. The output can swing rail-to-rail unloaded and typically can reach 80 mV from the rails, while driving a 600-Ω load (at 1.8-V operation).

The LMV981 and LMV982 devices offer shutdown capability for additional power savings.Ω
