我是不是买到假芯片了？理论上能输出负压的芯片不应该有对地二极管的。

Hello,

We meet an issue when we test AD5560 by below circuit. Attach picture is the test equipment.

System control register 0x1 is set to 0001 0010 0000 0000

DPS Register 1 0x2 is set to 1010 0010 0110 0000,

And we change Current range bit [13:11…

I would like to confirm AD5560 layout for DGND pin and AGND pins. In datasheet, “Analog and digital sections are separated and confined to certain areas of the board”.

However, we study MT-031 (Grounding Data Converters and Solving the Mystery…

• ### RE: AD5560 MEASOUT OUTPUT

Hi ,

I tried using google translate to understand your query. From there, it says that the AD5560 is being measured at rest. May I know more details about this specifically on what you meant by "at rest"? Additionally, I have other questions that needs…

Hi

I have two question need to help.

1) When writing 0V to register 0x8, the output will be 0.75V, and the output will be 0.75V more when writing different voltages (equal to a bias voltage of 0.75V added). How to solve this situation ?

2) During debugging…

• ### Behind the Kelvin alarm of AD5560

A   10V  voltage had been applied to  pin F7 (SENSE) . while  the force output was only  3.6V ( setting 5V ). Generally ,the FORCE should be the same with SENSE . isn't it?

So , what happened after…

• ### AD5560: How I understand the letter N of FNMV ?

Hi

How I understand the letter N of FNMV  in AD5560 datasheet ?

Can I do FIMV, that is force a constant current to measure voltage ?

Hi

I am working on AD5560 and I can not make AD5560 output voltage correctly.

My configurations are as follow:

AVDD = +28V,  AVSS = -5V   VREF = +5V

OFFSET_DAC code = 0x0     Force DAC(x1) = 0xFFFF

Force DAC's OFFSET AND GAIN REGISTERS  c…

• ### AD5560: How I set the register to clamp output current ?

Hi

How I set the register to clamp output current ? Such as set the output current 25mA output,  How i set the clamp current to 30mA or 20mA ?thanks
