3 Description

The LMV951 amplifier is capable of operating at supply voltages from 0.9 V to 3 V with specified specs at 1-V and 1.8-V single supply.

The input common-mode range extends to both power supply rails without the offset transition zone and input bias current 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 loading. At 1-V 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.
