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).
AD7671
Production
The AD7671 is a 16-bit, 1 MSPS, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. It contains a high...

Hi Jonathan,
I use ADR01 as the 10V reference. Resistance divider generate 2.5V reference voltage. I measured the reference pin. I think it is stable now.
I find voltage step when I change the input DC voltage, as in Figure 1. Blue line is the input DC voltage, and Green line is the voltage step of ADC output.
Thanks
