Hi Kiran,
The AD5724R would be a possible option in this case, as well as the AD5726.
They are both serial interface, quad DACs with compatible functionality to the DAC7615.
The AD5724R, as opposed to the AD5726, offers the SDO pin with which the…
Question:
我将AD5726写寄存器的函数（4通道一起次性完），通过双线SPI写进去的控制字只有1通道与4通道有效；
意思是AD5726_spi_write()一次性运行完就只有1通道与4通道有效；
但是我将AD5726_spi_write()用单步运行，等到程序运行完，4个通道都有效，DAC输出的值是对的。
我用示波器看了SDIN上面的数据，传输的数据是对的，为啥void AD5726_spi_write(void)一次性运行完就不对呢？
奇怪，希望得到指点！谢谢！
我SPI的CLK…
Hi Rob,
The 16-Lead Standard Small Outline Package [SOIC_W] of DAC8420 and AD5726 are pin compatible, however, please take note of the possible difference in specs and functionalities.
Cheers,

对于8通道的DAC，您可以考虑分辨率大于12bit的AD5362、AD5363、AD7841；
对于4通道的DAC，您可以考虑AD5725和AD5726；
In AD5726 datasheet ,Figure25 have OP1177 voltage follower.
And OP1177 output have 0.2uF capacitor.
But voltage follower OP1177 with output 0.2uF have only a few phase margine in ADIsim.
I think that this circuit is unstable.
Is this consideration…
I am using AD5726. On the datasheet there is reference input current (pag.3), for VREFN there is written -1mA (max).My question is: should I consider 1mA going inside the chip or 1mA coming from the chip ? What does minus means ?Thanks.Lucio
Hi Jonatan,
thank you for your reply. To make sure that I understood you correctly, please answer the following:
The "-10V min" limit, indicated in fig. 24, is missing from the "Absolute maximum ratings" table on page 7. It says:
thank you for your explanations.
About the glitch definition - what do you mean by "impulse glitch area"? The sum of areas under positive and negative parts, or their difference, as in the standard integral definition? If a glitch is a…
