LMV712

Low Power, Low Noise, High Output, RRIO Dual

Operational Amplifier with Independent Shutdown

General Description

The LMV712 duals are high performance BiCMOS opera-

tional amplifiers intended for applications requiring Rail-to-

Rail inputs combined with speed and low noise. They offer a

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

capacitive loads of up to 200pF without oscillation.

The LMV712 is guaranteed to operate from 2.7V to 5.5V and

offers two independent shutdown pins. This feature allows

disabling of each device separately and reduces the supply

current to less than 1µA typical. The output voltage rapidly

ramps up smoothly with no glitch as the amplifier comes out

of the shutdown mode.

The LMV712 with the shutdown feature is offered in space

saving 10-Bump micro SMD and 10-Pin Leadless Leadframe

Package (LLP) packages. It is also offered in 10-Pin MSOP

package. These packages are designed to meet the demands

of small size, low power, and low cost required by cellular

phones and similar battery operated portable electronics.
