      Precision ADCs
      26 July, 2018
      Hi,all Our customer will start to design the mixed signal circuits with AD7891ASZ-1. They are looking into circuits that supply the VDD separately for analog (pin4) and digital (pin13) power supply line. In the datasheet, from "Power Supply Bypassing and Grounding", One of the VDD pins (Pin 10 …

      Hi The customer has a question. Could you give us advice? The customer wants to know the impact when the conversion timing delayed. Does AD7891 stop work at that time? Does AD7891 restart? Regards,

      Hi sss, The VDD pins are the same function. These pin(VDD) should be power up at the same time, they supply the circuits inside. For power up sequencing the Vdd should be power up first followed by the Reference and digital input voltages. If the power ups sequence is …

      Hi all, Two IC that I am interested in are obsolete (AD7892AR-1 and SMP04ES). Both have suggested replacement AD789ARZ-1 and SMP04ESZ. As I understand the only difference is the original ICs are not RoHS compliant and the replacement are. However I can not find any evidence of my …
