LMV921 Single/ LMV922 Dual/ LMV924 Quad
1.8V, 1MHz, Low Power Operational Amplifiers with
Rail-To-Rail Input and Output
General DescriptionThe LMV921 Single/LMV922 Dual/LMV924 Quadare guar-
anteedto operate from +1.8Vto +5.0V supply voltagesand
have rail-to-rail input and output. This rail-to-rail operation
enablesthe userto make fulluseof theentire supply voltage
range. The input common mode voltage range extends
300mV beyondthe supplies andthe output can swing
rail-to-rail unloaded and within 100mV fromtherail with
600Ω loadat 1.8V supply. The LMV921/LMV922/LMV924
are optimized towork at1.8V which make themidealforpor-
tabletwo-cell battery-powered systemsand singlecell Li-Ion
systems.
The LMV921/LMV922/LMV924 exhibit excellent
speed-power ratio, achieving 1MHz gain bandwidth product 1.8V supply voltage with verylow supply current. The
LMV921/LMV922/LMV924are capableof driving 600Ω load
andupto 1000pF capacitive load with minimal ringing.The
LMV921/LMV922/LMV924’s highDC gainof 100dB makes
them suitableforlow frequency applications.
The LMV921 (Single)is offeredina space saving SC70–5
and SOT23–5 packages. The SC70–5 packageis only
2.0X2.1X1.0mm. These small packagesare ideal solutions
for area constrainedPC boards and portable electronics
suchas cellphonesand PDAs.
