  • ADS5553: Anti-aliasing filter for an ADC

    Resolved
    Part Number: ADS5553 Other Parts Discussed in Thread: TINA-TI , ADS5560 , LMH6552 , Hello I have an AD5553 ADC. I don't have any anti-aliasing filter so I need to put an first order RC filter at the input of AD5553. I've studied below document to design…

  • RE: OPA2625: How to improve SNR, HD2 and HD3 of an 18-bit SAR ADC when OPA2625 is being used to drive the differential inputs of ADC?

    Couple of quick things Akash, 1. Where is your DC bias current path for the V+ inputs to the op amps? 2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
