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/s 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.

in series with 100pF. Machine model, 0
in series with 100pF.
Note 3: Shorting circuit output to V
+
will adversely affect reliability.
Note 4: Shorting circuit output to V
-
will adversely affect reliability.
Note 5: The maximum power dissipation is a function of T
J(max)
,
JA
, and T
