Application Information
The LMV101/102/105/110 integrates a rail-to-rail op amp,
two internal gain-setting resistors and a V
one ultra tiny package, SC70-5 or SOT23-5. With its small
footprint and reduced component count for gain stage, it en-
ables the design of smaller portable electronic products,
such as cellular phones, pagers, PDAs, PCMCIA cards, etc.
In addition, the integration solution minimizes printed circuit
board stray capacitance, and reduces the complexity of cir-
cuit design.
The core op amp of this family is National’s LMV321.
1.0 Supply Bypassing
The application circuits in this datasheet do not show the
power supply connections and the associated bypass ca-
pacitors for simplification. When the circuits are built, it is al-
ways required to have bypass capacitors. Ceramic disc ca-
pacitors (0.1µF) or solid tantalum (1µF) with short leads, and
located close to the IC are usually necessary to prevent in-
terstage coupling through the power supply internal imped-
ance. Inadequate bypassing will manifest itself by a low fre-
quency oscillation or by high frequency instabilities.
Sometimes, a 10µF (or larger) capacitor is used to absorb

low frequency variations and a smaller 0.1µF disc is paral-
leled across it to prevent any high frequency feedback
through the power supply lines.
2.0 Input Voltage Range
The input voltage should be within the supply rails. The ESD
protection circuitry at the input of the device includes a diode
between the input pin and the negative supply pin. Driving
the input more than 0.6V (at 25˚C) beyond the negative sup-
ply will turn on the diode and cause signal distortions. For
applications that require sensing voltages beyond the nega-
tive rail, use the LMV111 with external gain setting resistors.
