I'm hope I can use the AD5270 or AD7272 as a replacement for as 10 Kohm (25 degres celcius) NTC resistor.
I would like to connect the AD5270/AD5272 to an Arduino-board (ATMEGA328). Does somebody have a diagram/Sketch for the connections?
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 7)
PB3: MOSI Connects to DIN (Pin 8)
PB2: SS Connects to SYNC (Pin 10)
Please note that the Arduino must be set to Mode 1 (CPOL = 0, CPHA = 1)
The AD5272 uses I2C communication:
PC5 - Connect to SCL on the AD5272 (Pin 9)
PC4 - Connect to SDA on the AD5272 (Pin 8) This should be pulled to the supply with an external pull up resistor
