Part Number: DAC161S997
Please take a look at the image above. Yellow line is SCK, cyan line is SDO, returning 0x85 from DAC. If we look at 0x01, 0x02 and 0x04 bits, it shows good transition - on the back front of SCK. But first bit, left one, 0x08 is…
Part Number: DAC161S997 I am using the DAC161s997 interfaced with a cortex M4 microcontroller for the SPI communication. The output is stuck at 3.37mA and as expected, changes to 21mA when i set the ERRLVL pin high. However, it is stuck in this error…
Part Number: DAC161S997 Other Parts Discussed in Thread: MSP430F5659 , Tool/software: WEBENCH® Design Tools Hi Team,
I'm using DAC161S997 evaluation board and interfaced SPI with MSP430F5659.
I'm able to set the DAC value like 15mA but DAC not maintaining…
Part Number: DAC8740H Other Parts Discussed in Thread: DAC161S997 , Hello team,
Here I sagar working on loop powered device. I need help in interfacing loop DAC8740H with DAC161s997. I am in trouble in given below points.
1) Help me in choosing capacitors…
Part Number: DAC161S997 Dear team,
Below the first picture is the programming. One Write command, and three read command. And the CSB(blue), SDI(yellow), SDO(green), SCLK(pink) waveforms are as following. We can see that, the SDO still has no change.…
Hi Amarr,
The LDO steps down the voltage from the loop supply to an appropriate level to supply DAC161S997. It may be possible for the device to regulate the loop current without it but it is not a practical use case for the device.
The error indicates…
Kevin,
Apologies for the delayed response.
Last week, we have received our customized PCB. I have tested DAC161S997 analog output stability on the same.
We got +/-0.01mA accuracy with our customized PCB. Which is more than enough for our application. …
Part Number: DAC161S997 Other Parts Discussed in Thread: DAC8740H Dear team,
When using the DAC161S997 to achieve 4-20mA current output and HART communication (with AD5700). Could you please help check whether the connection is right? Especially the HART…
