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 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 extends
300mV beyond the supplies and the output can swing
rail-to-rail unloaded and within 100mV from the rail with
600load at 1.8V supply. The LMV921/LMV922/LMV924
are optimized to work at 1.8V which make them ideal for por-
table 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 600load
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.
