  • RE: ADC3660: Synchronization of multiple ADCs in SDR output mode

    Resolved
    Hi Pieter, Yes, there will be a short transition/discontinuity in the NCO output as it changes to its new frequency. If holding the SYNC pin (or register) in a "high" state, the NCO will not be present. The main idea is to provide a pulse to quickly update…

  • RE: ADC3660: ADC3660 acquisition result is a constant value

    Hi, Can you share a picture of the noise you are seeing? What are the registers you are writing in order to configure the ADC in 1 wire decimation mode? Here is an FFT of the complex data with a 10 MHz NCO applied (no analog input present). Here is an…

  • ADC3444: DC-Coupled Input Recommendations

    Resolved
    Part Number: ADC3444 I'm curious to hear if anyone has used this ADC with a DC-coupled input. If so, did you use a differential amplifier to drive it? Which part? Any passive implementation options? Thanks.
