LMV101/102/105/110
Fixed-Gain Amplifiers
General Description
The LMV101/102/105/110 fixed-gain amplifier family inte-
grates a rail-to-rail op amp, two internal gain-setting resistors
and a V
+
/2 bias circuit into one ultra tiny package, SC70-5 or
SOT23-5. Fixed inverting gains of 1, 2, 5, and 10 are
available.
The core op amp in this series is an LMV321, which provides
rail-to-rail output swing, excellent speed-power ratio, 1MHz
bandwidth, and 1V/μs of slew rate with low supply current.
The LMV101/102/105/110 family reduces external compo-
nent count. It is the most cost effective solution for applica-
tions where low voltage operation, low power consumption,
space savings, and reliable performance are needed. It en-
ables the design of small portable electronic devices, and al-
lows the designer to place the device closer to the signal
source to reduce noise pickup and increase signal integrity.
