Part Number: DAC81408 Hi,
10.3.1.2.1 of the data sheet states "In both update modes a minimum wait time of 1 µs is required between DAC output updates.".
Is 1 us a mistake of tDACWAIT = 2.4 us?
Best Regards,
Nishie
Part Number: DAC81408 Hi,
I have a question regarding the accuracy of the DAC81408RHA's internal voltage reference.
According to the datasheet the initial accuracy should be +/- 2.5mV with an ambient temperature of 25°C. However, I have measured the…
Hi Sanjay,
First of all, I would like to thank you for your time and support over call to solve my problem.
Problem: Not Able to communicate with DAC81408.
Summary:
I was interfacing DAC81408 with AM2634 Quad Core Controller over SPI0 and setup to Core…
Hi Arek, The DAC81408 is pin-for-pin with a flexible output configuration. There is no power sequencing required for it as well. https://www.ti.com/product/DAC81408
Please let me know if you have any questions! Thanks, Lucas
Part Number: DAC81408 Hi Sir,
I am using DAC81408 in a Differential OUTPUT Mode +-10V. Also I have configured all the register sets as per the datasheet according to +-10V output.
And my Input voltage for the DAC is +-12V for the output of +-10V.
But…
Part Number: DAC81408 Other Parts Discussed in Thread: ADS8698 Is there a companion ADC for the DAC81408, I'm looking for an slow speed ADC for SPI interface for 1.8V logic and can handle bipolar inputs up to +/-10V. Thanks.
Part Number: DAC81408 What is the max output current and impedance of the sensor output. I've had a couple of board with output set to approx. 5V. Is there any reason they could be damaged or there is something in the part configuration?
Part Number: DAC81408 Hi Team,
Good day. My customer is responsible for developing a footprint for DAC81408, he wants to know the Footprint and Thermal Pad Dimension should he follow. Found this documents with which has package drawing of RHA (S-PVQFN…
Hi Akhilesh,
I don't have the equipment to put cap on the board. Also, I've been working with other DACs from TI and they work just fine, with caps away and my SPI script. I follow what is given in the datasheet and they work. This DAC has been causing…
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
