Hi,

I want use AD5254 digital potentiometer(http://www.analog.com/en/digital-to-analog-converters/digital-potentiometers/ad5254/products/product.html) in my project design, but I don't know how to program it.

I have never programmed I2C before…

Hi,

I'm facing a problem with digipot AD5254 on my board where I use them as a part of programmable amplifiers in op amp feedback path. Usually during power-on sequence (after turning power supply on) digipot wrongly writes values 0 or 255 in some…

Hi all,

I'd like to determine a suitable series resistor value put on I2C lines of AD5254.

Therefore, could you tell me typical drive strength (output current) of I2C interface of AD5254 and its IBIS model?

Best Regards,

TM

Hi, guys,

I need your help with I2C bit bang for AD5254 as my MCU doesn't support I2C.

I was trying to talk to AD5254 with its quick command write mode, but the digipot was not responding. I also tried to measure the resistance of RDACs, but it…

Hello,

I ordered two 50K versions of this chip and two 1K versions as well. According to the datasheet (http://www.analog.com/static/imported-files/data_sheets/AD5253_5254.pdf), they have identical pin-outs. The 50K responded to the power and grounding…

     Good morning.  I have a customer that is going to interface with the AD5254 via a Xilinx Spartan-6 FPGA and he has a couple of questions.

     1)  In Figure 29 of the data sheet, it indicates that the slave is generating the stop condition when all of the…

Preemptive apology for being so basic.

I'm using i2c to talk to an AD5254 from a RaspberryPi - spent last night rebuilding the kernel to enable device tree mode and add the digipot driver, and to my joy this morning I can see all of the eeproms and rdacs…

Hi,

My customers are considering using the AD5254.
So I got a question.

What voltages can I apply to the SCL pin and how many A can be applied?
"Digital Inputs and Output Voltage to GND" is stated as "0 V, 7 V", is this the same idea as the one confirmed…
