Part Number: DAC5662A Other Parts Discussed in Thread: LMH6703 , LMH6702
My customer developed display equipment and they found there is a ghost issue on Video output as below picture. You can see the adding line on right side of rectangle in…
Part Number: DAC5662A Hello.
below FPGA output spec.
FPGA output MIN voltage is 2V. and DAC5662A Vih spec is 2V.
Is there a problem with the communication between the two devices?
I wait for your answer. please reply about my question.
Other Parts Discussed in Thread: DAC5662A Hallo support team,
we want to use the DAC5662A in order to drive our outputsignal. The outputcurrent should be variable in a range of 20dB.
The outputcurrent is controlled by IOUTFS (IREF=32xVREF/RSET).
When looking at the AC timing, the parameter Tlat shows 4 clocks. Does this mean that the DAC is pipelined and intended to have a continuous clock feed? In other words, it is not intended for asynchronous writes.
Can someone please confirm or dispute…
We don't ESD rating for DAC5662. Anyhow I would recommend using DAC5662A instead which is same device but voltage requirement between AVDD and DVDD is relaxed. Here are ESD rating for DAC5662A.
Hi Patryk, Please take a look at DAC5652A. www.ti.com/.../dac5652a . The update rate is 275MSPS and it is parallel CMOS device. DAC5652A is 10 BIT device but the same family also has 12 BIT(DAC5662A) and 14 BIT (DAC5672A). Regards, Neeraj
Other Parts Discussed in Thread: DAC5662A Hey there,
I want to operate a DAC5662A with a clock frequency of 48MHz. The clock and the data comes from motherboard equipped with a Xilinx FPGA and the DAC will be on a analog I/O daughtercard.
I searched for…
Yes there is no problem with the figure 22 in the datasheet.
Here is the link to the application note. Section 2.3 talks about how the compliance voltage for the DAC is calculated.
Please recommend using the DAC5652A - it has same performance, but does not have as strict power sequence requirements. The AVDD and DVDD can come up independently. The AVDD-DVDD maximum voltage difference requirement on DAC5652 is +/-0.5V (AVDD…
