LMV111 Operational Amplifier with Bias Network
December 1999
LMV111
Operational Amplifier with Bias Network
General Description
The LMV111 integrates a rail-to-rail op amp with a V /2 bias
circuit into one ultra tiny package, SC70-5 or SOT23-5. The
core op amp of the LMV111 is an LMV321, which provides
rail-to-rail output swing, excellent speed-power ratio, 1MHz
bandwidth, and 1V/碌s of slew rate with low supply current.
The LMV111 reduces external component count. It is a cost
effective solution for applications where low voltage opera-
tion, low power consumption, space saving, and reliable per-
formance are needed. It enables the design of small portable
electronic devices, and allows the designer to place the de-
vice closer to the signal source to reduce noise pickup and
increase signal integrity.
