• AD5790 IOVCC vs. VCC

    Hi everyone,

    I will drive the DAC AD5790 over an SPI-Interface which is powered by 1V8!

    Actually, I've plan to powered the device with 1V8 on Pin IOVCC and 3V3 on Pin VCC.

    (VDD and VSS is driven by +7V5/-7V5)

    Can is DAC working fine with this power…

  • AD5790 low frequency noise

    Hi,

    I intend to use the AD5790 DAC for a precise DC voltage source. The datasheets says that the noise in the 0.1Hz to 10Hz bandwidth is 1.1uVpp (datasheet page 3 and 15).
    Further there is a noise density plot on page 16. I estimated the 1/f corner frequency…

  • AD5791 Versus AD5790 Vout Equation

    The AD5791 and AD5790 DACs appear to be very similar devices, yet their respective data sheets have different equations for the output voltage.

    The AD5791 equation seems to be a bit of an anomaly as most other ADI DACs do not include the minus 1 term…

  • EVAL-AD5790 Help

    Hi, in my setup, I used an Arduino mega to send command bitcodes to the EVAL-AD5790 to set voltages, but I think I overloaded them by entering too high of a voltage (around 10V). When I used them to output 5V previously, they worked perfectly. However…

  • Controlling EVAL-AD5790 with Arduino MEGA microcontroller

    Hi, I'm trying to control an EVAL-AD5790 board with an Arduino MEGA using SPI communication, essentially to control the output voltage using a desktop which plugs into the Arduino. I'm a beginner in this field and am a high schooler, so if you see…

  • AD5790是否损坏

    AD5790在复位状态下管脚电平分别如下:

    管脚1:6.0mv

    管脚2:   5.02v

    管脚4:3.3V

    管脚16: -0.5mv

    管脚20: 16.3mv

    管脚24:  5.3mv

    另外一个AD5790复位状态下管脚电平分别如下:

    管脚1:0mv

    管脚2:   5.02v

    管脚4:3.3V

    管脚16: 0mv

    管脚20: 0mv

    管脚24:  0mv

    前者DA输出浮动,后者稳定。

    前一个AD5790是否损坏,如果未损坏如何确定原因并修复,如果损坏,有哪些因素造成的?
