High-Side Current Sense Amplifier DescriptionThe LMV93x-N family (LMV931-N single, LMV932-N
dual and LMV934-N quad) are low-voltage, low-
power operational amplifiers. The LMV93x-N family
operates from 1.8-V to 5.5-V supply voltages and
have rail-to-rail input and output. The input common-
mode voltage extends 200 mV beyond the supplies
which enables user enhanced functionality beyond
the supply voltage range. The output can swing rail-
to-rail unloaded and within 105 mV from the rail with
600-Ω loadat 1.8-V supply. The LMV93x-N devices
are optimizedto workat 1.8 V, which make them
ideal for portable two-cell, battery-powered systems
and single-cell Li-Ion systems.
LMV93x-N devices exhibit an excellent speed-power
ratio, achieving 1.4-MHz gain bandwidth productat
1.8-V supply voltage with very low supply current.
The LMV93x-N devices can drivea 600-Ω load andto 1000-pF capacitive load with minimal ringing.
These devices also havea high DC gainof 101 dB,
making them suitable for low-frequency applications.
The single LMV93x-Nis offeredin space-saving 5-pin
SC70 and SOT-23 packages. The dual LMV932-N
arein 8-pin VSSOP and SOIC packages and the
quad LMV934-N arein 14-pin TSSOP and SOIC
packages. These small packages are ideal solutions
for area constrained PC boards and portable
electronics suchas mobile phones and tablets.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe datasheet.
