    RE: THS4551: Flicker noise

    Hello Mochizuki, Our devices are tested to eliminate noise as much as reasonably possible, however due to the random nature of popcorn noise it possible for these issues to occur. Would you be able to share with me your schematic offline? Will send...

    RE: THS4551: Circuit Designing.

    Hello Shibin, ADC performance is similar, the major difference here will be the polarity of your reading. See example below, if AINP and AINN were switched here then the first peak of Vdiff would be -1V rather than 1V. Best, Hasan Babiker

    RE: THS4551: Output offset problem when doing ESD test

    Hi Vincent again, R250 between the inputs is no good idea. But a 1M resistor from each input (V1+ and VI-) to signal ground (AGND) is. By the way, have you connected VI- to AGND during the test or have you let it float? Kai
