LMV924

LMV921 Single/ LMV922 Dual/ LMV924 Quad 1.8V, 1MHz, Low Power Operational Amplifiers with Rail-To-Rail Input and Output December 1999 LMV921 Single/ LMV922 Dual/ LMV924 Quad 1.8V, 1MHz, Low Power Operational Amplifiers with Rail-To-Rail Input and Output General 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 common mode voltage range extends 300mV beyond the supplies and the output can swing rail-to-rail unloaded and within 100mV 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 1000pF capacitive load with minimal ringing. The LMV921/LMV922/LMV924’s high DC gain of 100dB makes them suitable for low frequency applications. The LMV921 (Single) is offered in a space saving SC70–5 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.
