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.
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.
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.
In shutdown mode the LMV951 consumes less than 50 nA of
supply current.
