LMV922 Datasheet | National Semiconductor

Description The LMV921 Single/LMV922 Dual/LMV924 Quad are guaranteed to operate from +1.8V to +5.0V supply voltages and have rail-to-rail input and output. This rail-to-rail operation enables the user to make full use of the entire supply voltage range. The input mon mode voltage range extends 300m V beyond the supplies and the output can swing rail-to-rail unloaded and within 100m V from the rail with 600Ω load at 1.8V supply. The LMV921/LMV922/LMV924 are optimized to work at 1.8V which make them ideal for portable two-cell battery-powered systems and single cell Li-Ion systems. The LMV921/LMV922/LMV924 exhibit excellent speed-power ratio, achieving 1MHz gain bandwidth product at 1.8V supply voltage with very low supply current. The LMV921/LMV922/LMV924 are capable of driving 600Ω load and up to 1000p F capacitive load with minimal ringing. The LMV921/LMV922/LMV924’s high DC gain of 100d B makes them suitable for low frequency applications. The LMV921 (Single) is offered in a space saving SC70- 5 and SOT23- 5 packages. The SC70- 5 package is only 2.0X2.1X1.0mm. These small packages are ideal solutions for area constrained PC boards and portable electronics such as cellphones and PDAs.
