• RE: AD5144 I²C register addresses and read commands

    There is no 16 bit register address. 

    The device I2C is designed as per the I2C specification. Specification – I2C Bus (i2c-bus.org)

    Refer to the I2C timing diagrams in Fig 45 in the DS AD5110/AD5112/AD5114 (Rev. B) (analog.com)

  • RE: AD527x resistance calculation

    Hi Jan,

    People usually get confused with wiper resistance. Let me try and explain it clearly as possible.

    Wiper resistance is the resistance of the switch connected to the wiper terminal. Please refer the figure given below:

    The on resistance of switch…

  • AD527x resistance calculation

    Question:

    I have a problem with understanding the AD527x datasheet in the point, where the relation between code written to the chip and its actual resistance is explained: Table 1 states, that the wiper resistance is between 35 and 70 Ω. Later, in the…

  • AD5110 Power-On Reset

    Hello All,

     

    I have some questions for AD5110 Power-On Reset.

     

    Q1) What is the threshold voltage value for POR?

    And which pin’s voltage level does monitor for? VLOGIC or both VLOGIC and VDD?

    (Please see the attached picture for your reference)
