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).

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 have a buffer with 47uF capacitor after the resistant divider to drive the 2.5V reference pin. I changed the sapmling rate to 1kHz and the result had no change.
I'll outoff office for Chrismas.I'll back next week.
Many Thanks
