Hi Louis,
I am going to close this thread and focus on your other post: https://e2e.ti.com/support/data-converters/f/73/t/855350 as I feel these are really the same problem. I will also reach out to you over email shortly.
Thanks,
Paul
Hi Lou,
As we have continued this discussion over email, I would like to close the thread. I will summarize our discussion for future readers:
Basically, the way tDACWAIT must be interpreted is as the delay between the latch edge and the CS falling edge…
Part Number: DAC81408
The datasheet says to connect a 330pF cap from REFCMP to REFGND, but the EVM connects 1000pF. Is it safe to assume the datasheet means at least 330pF?
The datasheet also says to use at least 150nF between REF and REFGND to filter…
Hi Datta,
Please provide below details to debug the issue -
a) jumper configuration on the DAC91408EVM hardware
b) supply values for the DAC81408
c) are you able to communicate with the DAC81408 device ?
d) if yes, what are the SPI commands written to DAC81408…
Hi Koshi-san,
This PWL waveform will not be possible with DAC81408 because of-
1. slew rate for DAC81408 is only 4 V/us
2. minimum wait for the sequential update for DACx voltage output is 2.4 us
I would recommend to suggest the customer DAC80508 or…
Sorry ，I made a mistake。, I measured OUT0-OUT3 and OUT12-OUT15，these pins are NC on DAC81408，the correct output is form OUT4-OUT11.
It works well ，thank you ！
Part Number: DAC80508 Other Parts Discussed in Thread: DAC81408 , SN74LV1T125 , Dear, support Team. Our customer plans to drive the analog output of the DAC81408 as a power supply for the SN74LV1T125. The SN74LV1T125 drives a signal speed of 10Mbps and a load…
Hi Sanjay,
Offset Error(±0.05%FSR min/max) and Gain Error(0.06 %FSR min/max) are specified at TA = –40°C to +125°C.
Could you show them at 25℃？ I'd like to calculate their drifts from at 25℃ with "Offset error temperature coefficient…
Part Number: DAC8718EVM Other Parts Discussed in Thread: DXP , DAC81408 , DAC81416 , DAC80508 , DAC8728 , DAC8718 , DAC8568 I am looking for a 16bit at least 8 channel voltage output DAC.
I want to be able to test with data in a file and stream it and maintain…
Part Number: DAC81408EVM Hi Experts,
Our customer dac81408 device. However he has no usb2any connector. He is asking if he can use rs232/442/485 as a usb2any device dac810408 EVM?
As far as I know this will not work as the GUI will not work without the…
