DESCRIPTION
LMV981-N/LMV982 are low voltage, low power
operational amplifiers. LMV981-N/LMV982 operate
from +1.8V to +5.0V supply voltages and have rail-to-
rail input and output. LMV981-N/LMV982 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. LMV981-
N/LMV982 are optimized to work at 1.8V which make
them ideal for portable two-cell battery powered
systems and single cell Li-Ion systems.
LMV981-N/LMV982 offer a shutdown pin that can be
used to disable the device and reduce the supply
current. The device is in shutdown when the SHDN-
pin = low. The output will be high impedance in
shutdown.
LMV981-N/LMV982 exhibit excellent speed-power
ratio, achieving 1.4MHz gain bandwidth product at
1.8V supply voltage with very low supply current.
LMV981-N/LMV982 are capable of driving a 600Ω
load and up to 1000pF capacitive load with minimal
ringing. LMV981-N/LMV982 have a high DC gain of
101dB, making them suitable for low frequency
applications.
LMV981-N is offered in space saving 6-Bump
DSBGA, SC70-6 and SOT-23-6 packages. The 6-
Bump DSBGA package has only a 1.006mm x
1.514mm x 0.945mm footprint. LMV982 is offered in
space saving VSSOP-10 package. These small
packages are ideal solutions for area constrained PC
boards and portable electronics such as cellular
phones and PDAs.
