LMV931 Single / LMV932 Dual / LMV934 Quad
1.8V, RRIO Operational Amplifiers
General Description
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 600Ω load 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/
LMV934 are capable of driving a 600Ω load 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.
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.
