  • RE: ADS4449: Schematic review

    JH, The ADS4449 is a LVDS output device. You need to remove all series 22 Ohm resistors on the output data lines and the output clocks and replace them with a single 100 Ohm resistor that will be connected across every +/- pair 2746.Transformers.ppt if…

    Resolved
    Yinon, Yes, using a 1:N transformer will allow you to increase the signal swing without adding noise as this is a passive device. You will need to be careful when choosing a transformer as the linearity will vary from model to model. I have attached a…

  • ADC clock on TSW4100

    Resolved
    Other Parts Discussed in Thread: ADS5545 I have noticed that in the factory configuration of the TSW4200 the clock for the ADS5545 is generated single ended in the CDMC7005 then buffered, filtered and then converted in a differential signal. What is the…

  • 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…
