Dear Sir/Madam, We have a question about the Vcc of ADM3101E RS232-transceiver.
When the raise time of Vcc is 170msec, is a problem in operation of ADM3101E?.
It would be greatly appreciated if advice could be gotten.
Best Regards,Kou
Hi Teruamsa,
For the application setup described, i think that the current from Viso of ADuM6211 meets the requirements of VDD2 of ADuM6211 and VCC of ADM3101E.
VDD2 of ADuM6211:power supply current : 2.3 mA Max.
VCC of ADM3101E:power supply current…
Hi
Is there an EVB for the ADM3101E?

Hi,
Is it acceptable to use ceramic, non-polarized capacitors for C1-C5 in figure 1 of the datasheet?
Further, can this be generalized for most RS232 transceivers?
Hi Raquib,
Do you require isolated power as well as isolated data? If you don't require isolated power then you could disable the DC-DC converter on-chip by supplying the VISO side with a separate 3.3V supply. This would greatly reduce the power consumption…
Hi patelvijay12007,
In relation to the interface between the loop and the HART modem figure 27 of the AD5700/AD5700-1 datasheet may be of use to you (there is additional information on this circuit in the datasheet as well):
In terms of the HART software…
这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?
