  RE: INA181: VREF impedance

  Hello Peter, The REF pin is connected to one of the internal feedback resistors which set the overall INA181 gain, and is dependent on gain version. Please see the functional block diagram image below. The absolute values of these resistors...

  RE: non phase reversal op amps

  The Analog Applications Journal article Op amps with complementary‐pair input stages: What are the design trade‐offs? says: Phase inversion (or phase reversal) was a common issue with amplifiers that use this architecture … It occurs when the...

  RE: LMV321: Input CM spec

  Lutz, Technically minimum would be correct. However, it is common to use a "Recommended Operating Conditions" mentality for this spec. So applications should limit inputs to 1.7V, although 1.9V typically works (but not always) If both inputs...

  RE: LMV321: LMV321IDCKR not rail-to-rail?

  Hello Vilen, LMV321 is not a rail to rail input device. It is rail to rail output, although the VOL doesn't ever get to the rail. Once input is within about 0.7V of Vcc the input stage cuts off and the output can do multiple things, clamp to Vcc...

  RE: LMV321: Can LMV321 be used to a comparator ?

  Aggil, Kai comments are valid. When LMV321 has both inputs above the common mode range and the op amp is in open loop configuration, the output will be either near 0V or 5V. The input stage is cutoff so the next internal stage will have a zero difference...

  RE: LMV321: In the process of production, the IC LMV321 used for amplification function is 16% bad, and there will be noise.

  Hello Clark, The signal level in this application is low and the amplifier gain is high. So noise can be a significant factor. There will be some improvement by using the next generation LMV321A that is a low noise CMOS process. If even lower noise...
