3 Description

The LMV712-N devices are high-performance

BiCMOS operational amplifiers intended for

applications requiring rail-to-rail inputs combined with

speed and low noise. They offer a bandwidth of

5 MHz and a slew rate of 5 V/μs, and can handle

capacitive loads of up to 200 pF without oscillation.

The LMV712-N is ensured to operate from 2.7 V to

5.5 V and offers two independent shutdown pins. This

feature allows disabling of each device separately

and reduces the supply current to less than 1 μA

typical. The output voltage rapidly ramps up smoothly

with no glitch as the amplifier comes out of the

shutdown mode.

The LMV712-N with the shutdown feature is offered

in space-saving 10-pin DSBGA and 10-pin WSON

packages. It is also offered in 10-pin VSSOP

package. These packages are designed to meet the

demands of small size, low power, and low cost

required by cellular phones and similar batteryoperated

portable electronics.
