LMV951

1V, 2.7 MHz, Rail-to-Rail Input and Output Amplifier with

Shutdown Option

General Description

The LMV951 amplifier is capable of operating at supply

voltages from 0.9V to 3V with guaranteed specs at 1V and

1.8V single supply.

Features

(Typical 1.0V supply, unless otherwise noted)

n Guaranteed 1V single supply operation

n Wide bandwidth

The input common mode range extends to both power sup-

ply rails without the offset glitch and input bias current phase

reversal inherent to most rail to rail input amplifiers.

n No V_OSglitch over the input CMVR

n No input I_BIAScurrent reversal over V_CMrange

n Buffered output stage

Contrary to a conventional rail to rail output amplifier the

LMV951 has a buffered output stage providing an open loop

gain which is relatively unaffected by resistive output load-

ing. At 1V supply voltage, the LMV951 is able to source and

sink in excess of 35 mA and offers a gain bandwidth product

of 2.7 MHz.
