I am using a DAC (AD5422) in an application where there is the possibility of a customer misusing this by tying all the analog outputs together, where the outputs are at different potentials, and possibly in different modes (-5V to +5VDC and 4-20mA).…

I have a question regarding the SPI timing for the AD5422 in Daisy Chain mode vs. Read/Write in normal standalone mode.  Here is a copy of the Timing characteristics from Rev O. of the datasheet:

Question 1:  Why is T5 in write mode 5uS, while in daisy…

Hi,

I'm trying to get an AD5422 working. I can't get an output signal or register data from a readback.

 Here it the schematics I use:

DVcc = 3.36V, AVdd = 11,93V, AVss = 0V, Clear = 0V;

Vout stays always about 16mV.

1. I removed IC13, R57 and…

i currently have an evaluation board of the AD5422, and noticed that when i supply the AVdd first before the DVcc it only gives me an error of +/- 2mV(voltage output: 0-5V range) and when i supply DVcc first before AVdd it gives me an error of about 2V…

Hi there,

I have some question about AD5422.
Would you give me some advice?

#1,
According to the datasheet, AD5422 has a Aversion and Bversion.
What are the differences between Aversion and Bversion.
It looks like that Bversion has a better TUE spec.
And…

Hello

Im trying to get the AD5422 to work but the output stays constant at 1V no matter what i write into the data register.

The output is 0 to 5v range.

This is my schematic:

I connected -Vsense to ground and +Vsense to Vout but no change.

My SPI looks…

hi, Sir:

I want to use AD5422 to export sinwave and change its amplitude like P1.

But I find that the DAC output is like P2.

Can you help me to solve this issue? thanks.

Help me please. may be i don't see something in apNote but  i don't understand how to work with ad5422.

The listing of my programm is only:

while (1)
{
GPIOB->BRR=1<<7;
GPIOB->BSRR=1<<8;
GPIOB->BRR=1<<9;

GPIOB->BRR…
