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 600

Ω 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 600

Ω 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.
