LM6172QML: LM6172 MDR or 5962F9560401V9A (Die)

Part Number: LM6172

We have some question regarding the data mentioned in the Datasheet.

  1. Only Typical AC electrical parameters are provided in datasheet table. Are there any min/max bounds they can provide? Of particular interest are noise, distortion and slew rate.
  2. Is the slew rate sensitive to the common mode voltage of the amplifier?
  3. Do they have any radiation test data for these parameters?

Can you please help us in getting the above information?

Thank you so much for your time.

    Hi Mukesh,

    When we establish min/max values for parameters, a representative sample of devices are measured, and a statistical distribution is established we don't actually measure these limits in lab. If they are not listed in the datasheet as min/max limits, it is very likely they are not measured in the test program and have not been characterized for variation limits. With most AC parameters, we measure these during our validation process but do not measure in the test program and therefore do not establish a min/max for these parameters.

    The slew rate of the amplifier should not be sensitive to the common mode voltage at the input. Slew rate usually has a higher dependence on the supplies as well as the input rise time and amplitude. A possible scenario where common mode voltage could affect the slew rate performance would be if the voltage is limiting the voltage headroom of the device, not allowing the device to fully slew.

    The radiation data we have for this device can be found in the LM6172QML-SP product page under Technical documentation, the link to the report can be found here. There is also SEE data for this device and can be found here. There is one section specific to the LM6172 device.

    Best Regards,
