DESCRIPTION/ORDERING INFORMATION
The LMV712 dual operational amplifier is a high-performance BiCMOS operational amplifier intended for
applications requiring rail-to-rail inputs, combined with speed and low noise. The device offers a bandwidth of
5 MHz, a slew rate of 5 V/μs, and operates with capacitive loads of up to 200 pF without oscillation.
The LMV712 offers two independent shutdown (1SD, 2SD) pins. This feature allows disabling of each device
separately and reduces the supply current to less than 1 μA typical. The output voltage rapidly and smoothly
ramps up with no glitch as the amplifier comes out of the shutdown mode.
The LMV712 is offered in the space-saving SON (DRC) package and in an MSOP (DGS) 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.
