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

andaV

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.
