Hi,
I am unable to find the initialization sequence for AD5274 with the stm32.
Please provide me any user guide to use the AD5274 along with the stm32 controller (non os).
Thank you.
We are using the ad5274 device to control an LCD contrast pin. I have successfully instantiated the ad5274 linux driver. The driver exposes a couple of files in /sys/bus/i2c/devices/000-02c. The files of note are rdac0, otp0en, and otp0. I can't find…
can you please tell me what is the wiper setting time of AD5272/AD5274 Digital Rheostat?
I have figured out what's going on here.
The amplifier I'm using is TI INA333, which has strict capacitance requirement on the RG pins. I'm using AD5274 on RG pins to set the gain. However, the intrinsic capacitance on the A and W pins are 1) too…
Hello,
In my application I will need four digital potentiometers (AD5272/AD5274), which I will connect parallel. Could you tell if that is possible? If it is possible, you can give instructions how I will manage this.
Thank you,

Currently reading the datasheet of these components, I wish to ask you some more information about the power-up sequence.
On page number 24 of the datasheet (revision C), I can read that the ideal power-up sequence is : 1.VSS, 2. VDD and then…
Hello All,
I tried to change the RDAC Register value of AD5274BRMZ-20 (20K-Max) through I2C. But the resistance between the A & W pins is always constant to 9.25K(Mid Value).
I have sent the following Values through I2C.
Device Address : 0X2C (I have…
Hi Peter,
Could you clarify your problem? ie. the fuses wont get programmed, fuses blown correctly but the part does not power in the correct position...
Additionally,
do you read bit C3 after programming the part?
do you read the last memory location…
