Hello i wanto tu use a Arduino Uno or a ESP8266 thing dev with a ad5293.
It's need a levelshifter?
Could you share the code and the schematic?
Thanks

Greetings,
I have been trying to use some AD5293 digpots to get the complete range of some ADC equipment. It works mostly fine, but for some reason, there seems to be a small error, that is, if I set the digpot to 100, most of the time when I read back…
From the data sheet:
Note 4 warns these are design figures.
I am using the 20k version in a network that has some capacitors connected to the digipot, to calibrate the phase of the circuit. The problem is the capacitances of the network the digipot…
Hi,
I am trying to use an AD5293 but it doesn't seem to behave correctly.
First the RDY output pin didn't seems to toggle.
Second, I notice that the EXT_CAP pin is at 0V.
The other supply levels are fine.
Channel 1 is SYNC
Channel 2 is …
When you use AD5293 as a rheostat, one of the terminals either A or B will be open. So, only Raw or Rwb will be applicable but not both.
Yes, the bandwidth will increase, but it will be limited by the internal circuitry.
Dear All:
I Need AD5293 reference schematic to design my PCB ,can you rpovide refer. document to me? thanks
Best Regards,

I have a few question on AD5293 in datasheet.
1.Based on formula on page 20 in the datasheet about how to calculate RWB and RWA, I have following two questions.
I received this question from a customer:
We are having problems with the AD5293 digital pot. We are having problems with it on a prototype board. It consistently locks up the SPI bus (specifically the MISO pin).
Initially, we took no precautions in…
Hello, I am attempting to use an AD5293 digital potentiometer using an ATmega328 microcontroller using Arduino (C++). I have it surface-mounted to my PCB in the feedback loop of an LM2676 switching mode power supply. I am only attempting to write data…
hello,
I am using the AD5293 (100K) digital potentiometer along with the AD8675 Op amp. I want to have a variable gain, to amplify the output of a tranformers.
+Van= +11.2V
-Van= -11.2V
The input signal is 50Hz.
I set the gain to 128, programming…
