The LMV921 Single/LMV922 Dual/LMV924 Quad are guar-anteed 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 common mode voltage range extends300mV beyond the supplies and the output can swing rail-to-rail unloaded and within 100mV from the rail with600\Omega 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. TheLMV921/LMV922/LMV924 are capable of driving 600\Omega load and up to 1000pF capacitive load with minimal ringing. TheLMV921/LMV922/LMV924's high DC gain of 100dB makes them suitable for low frequency applications. The LMV921 (Single) is offered in a space saving SC70-5and 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 Pd As.
