• I2C Read sequence AD5144A

    Hi 

     AD5144A Datasheet don't have read sequence example.

    I refer AD5671 Datasheet.

    Is AD5144A's sequence same as Figure 61 in AD5671 Datasheet.

    Start⇒ slave address (W)⇒ACK ⇒command and address bits⇒ACK⇒ slave address (R)

    ⇒respond ……

  • i2c programming AD5144A in Linux

    This is my first attempt with i2c, so need basic help.

    I have a circuit with AD5144A and attempting to communicate through linux using i2c-tools and cpp.  I have found examples on the net, but nothing seems to work.  Wondering if a simple working example…

  • AD5144A digipot programming via Arduino I2C

    I am using the AD5144A 100kΩ digipot (among other AD parts) to be controlled by an Arduino Mega 2560. The Arduino is capable of creating a 100 kHz I2C bus and programming slave devices, such as the AD5144A. However, using the provided 7-bit addresses…

  • AD5144A+LT3476使用问题

    现在做一款调光的设备。使用LT3476+AD5144A配合。利用LT3476输出的Vref(1.05V)做AD5144A A端的参考电压。发现Vref只有0.8V左右。将LT3476于AD5144A断开发现Vref输出是正常的1.05V。AD5144A那边要求的上电时序等都是对的但是还是会把Vref拉到0.8V。请问是什么原因造成的。

  • AD5144A Digital potentiometer power supply connection for single +3.0V/0V use

    Hello

    I am planning to use AD5144A as digital pot for OpAmp Gain control.

    Analog input voltage and single power (ex. +3.3V/0V),

    then, is following usage correct or not?

    Could you please tell me power supply connection ?

  • RE: AD5144R don't care command behavior

    Hi Miguel-san

    I2C address is 01010000 00000001 XXXXXXXX.(AD5144A)

    But this command is not for AD5144A and  is for other  IC in same slave address.

    I worry about some malfunction.

    By the way , I have AD5524 evaluation board and I tried to evaluate NOP…

  • RE: End resistance

    You're welcome.

    You may want to check the AD5144A which offers guaranteed low resistor tolerance errors of ±8%. If you want to look at more options, you may use the parametric search for your convenience.
