LMV951 - 1V, 2.7 MHz, Rail-to-Rail Input and Output Amplifier with Shutdown Option
Datasheet Packaging Samples & Pricing Reliability Models Knowledge Base

Features

(Typical 1.0V supply, unless otherwise noted)

  • Guaranteed 1V single supply operation
  • Wide bandwidth
  • No VOS glitch over the input CMVR
  • No input IBIAS current reversal over VCM range
  • Buffered output stage
  • High output drive capability
  • Output short circuit

    Sink current

    35 mA

    Source current

    45 mA
  • Rail-to-rail buffered output

    @ 600Ω load

    32 mV from either rail

    @ 2 kΩ load

    12 mV from either rail

    • Temperature range

    −40°C to 125°C

    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 supply 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 loading. More...

    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 supply 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 loading. 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.

    Reliability Metrics

    Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)
    LMV951MKVIP50CLZ301755003150001289382110
    LMV951MKXVIP50CLZ301755003150001289382110

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
