LMV981 Single / LMV982 Dual
1.8V, RRIO Operational Amplifiers with Shutdown
General Description
LMV981/LMV982 are low voltage, low power operational
amplifiers. LMV981/LMV982 are guaranteed to operate from
+1.8V to +5.0V supply voltages and have rail-to-rail input
and output. LMV981/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/
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/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.
LMV981/LMV982 exhibit excellent speed-power ratio,
achieving 1.4MHz gain bandwidth product at 1.8V supply
voltage with very low supply current. LMV981/LMV982 are
capable of driving a 600Ω load and up to 1000pF capacitive
load with minimal ringing. LMV981/LMV982 have a high DC
gain of 101dB, making them suitable for low frequency ap-
plications.
LMV981 is offered in space saving 6-Bump micro SMD,
SC70-6 and SOT23-6 packages. The 6-Bump micro SMD
package has only a 1.006mm x 1.514mm x 0.945mm foot-
print. LMV982 is offered in space saving MSOP-10 package.
These small packages are ideal solutions for area con-
strained PC boards and portable electronics such as cellular
phones and PDAs.
