推荐使用AD5270， 1024抽头， 20Kohm 100Kohm可选
Can you tell me about the application you are designing?
The AD5270 uses SPI communication, while the AD5272 uses I2C communication:
PB5: SCLK Connects to SCLK on the AD5270 (Pin 9)
PB4: MISO Connects to SDO (Pin…
AD5270/1 has two modes of operation:
1. R-Performance mode: where the resistor tolerance can be upto 1% based on table 2 and 3 in the Datasheet.
2. Normal Mode: where the typical resistor tolerance is 15%.
By default the R-performance is…
Customer has designed in the AD5270. For production, they would like to have a way to program the devices using a PC (i.e. via USB). They have the Evaluation board for the AD5270/AD5272 devices and were wondering if it can be re-purposed to achive the goal…
Thank you for your reply. i using 3series AD5270 for test circuit.
I modified it the way you suggested. AD5270 still doesn't change resistor value . Please refer followings;
< Figure 1. t5,t6 timing>
< Figure 2. 0x1C03…
Thanks, so AD5270 is not function equivalent to AD5239. I missed it.
Hello, so we have an application where we use two AD5270 and i can get one to talk to me but i can't get the other one to change it's wiper position from mid-scale or anything. i've tried on multiple boards and still one works and one doesn't respond…
