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 offers two independent shutdown pins. This

feature allows disabling of each device separately and re-

duces 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 lead MSOP

package. These packages are designed to meet the de-

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

cellular phones and similar battery operated portable elec-

tronics.
