LMV101/102/105/110

Fixed-Gain Amplifiers

General Description

Features

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.

(For 5V Supply, Typical Unless Otherwise Noted)

n Fixed inverting gain available −1,−2,−5,−10

n DC gain accuracy 2.7V supply

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.

n Space saving packages

n Industrial temperature range

n Low supply current

n Rail-to-Rail output swing

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.

n Guaranteed 2.7V and 5V performance

Applications

n General purpose portable devices

n Mobile communications

n Battery powered electronics

n Active filters

n Microphone preamplifiers
