AD7671 Output has step

Hi,

 When I use AD7671 to convert signal (1Hz to 1kHz), I found steps in the output.

Attachment figure 1 is the waveform, where green line is input of AD7671;yellow line is the output of AD7671 (a DCA output, the DAC operated well).

  • Hi Jonathan,

    I found ADC have different operating range in one step, in Figure 1. The signal in circle A is the normal operating range, and the signal in circle B is the abnormal operating range. The step is form by the abnormal operating range.

    But I don't know the source of the range B.

    Thanks
