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
Rail-to-Rail inputs combined with speed and low noise. They
offer a bandwidth of 5MHz and a slew rate of 5V/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.
