7 / 42 page  2-1 LMV921 Qualification Package 2.0 DEVICE INFORMATION LMV921 1.8V, 1MHz, Low Power Operational Amplifier with Rail-To-Rail Input and Output in SC70-5 package General Description The LMV921 is guaranteed to operate from +1.8V to +5.0V supply voltages and has 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 volt- age range extends 300mV beyond the supplies and the out- put can swing rail-to-rail unloaded and within 100mV from the rail with 600 Ω load at 1.8V supply. The LMV921 is opti- mized to work at 1.8V which makes it ideal for portable two-cell battery-powered systems and single cell Li-Ion sys- tems. The LMV921 exhibits excellent speed-power ratio, achieving 1 MHz gain bandwidth product at 1.8V supply voltage with very low supply current. The LMV921 is capable of driving 600 Ω load and up to 1000pF capacitive load with minimal ringing. The LMV921’s high DC gain of 100dB makes it suit- able for low frequency applications. The LMV921 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.
