THS4551: TINA Simulation error
Part Number:
THS4551
I have 2 TINA circuits. The first (CCT1 - S2 for Forum) the transient Analysis works fine. However the 2nd (CCT2 - S2 for Forum) gives me an irregular circuit error as follows :- The only change I made was RG1 & RG2 from...

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
