LMV931 Single / LMV932 Dual / LMV934 Quad  
1.8V, RRIO Operational Amplifiers  
General Description  
Features  
The LMV931/LMV932/LMV934 are low voltage, low power  
operational amplifiers. LMV931/LMV932/LMV934 are guar-  
anteed to operate from +1.8V to +5.0V supply voltages and  
have rail-to-rail input and output. LMV931/LMV932/LMV934  
input common mode voltage extends 200mV beyond the  
supplies which enables user enhanced functionality beyond  
the supply voltage range. The output can swing rail-to-rail  
unloaded and within 105mV from the rail with 600load at  
1.8V supply. The LMV931/LMV932/LMV934 are optimized to  
work at 1.8V which make them ideal for portable two-cell  
battery powered systems and single cell Li-Ion systems.

LMV931/LMV932/LMV934 exhibit excellent speed-power ra-  
tio, achieving 1.4MHz gain bandwidth product at 1.8V supply  
voltage with very low supply current. The LMV931/LMV932/ Applications  
LMV934 are capable of driving a 600load and up to  
1000pF capacitive load with minimal ringing. LMV931/  
LMV932/LMV934 have a high DC gain of 101dB, making  
them suitable for low frequency applications.

n Portable/battery-powered electronic equipment  
n Supply current monitoring  
The single LMV931 is offered in space saving SC70-5 and  
SOT23-5 packages. The dual LMV932 are in MSOP-8 and  
SOIC-8 packages and the quad LMV934 are in TSSOP-14  
and SOIC-14 packages. These small packages are ideal  
solutions for area constrained PC boards and portable elec-  
tronics such as cellular phones and PDAs.
