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 operate
from +1.8V to +5.5V 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 ra­tio, 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 5-Pin SC70 and
SOT23 packages. The dual LMV932 are in 8-Pin MSOP and
SOIC packages and the quad LMV934 are in 14-Pin TSSOP
and SOIC packages. These small packages are ideal solu­tions for area constrained PC boards and portable electronics
such as cellular phones and PDAs.
