Hello TI,
I am working on the design of the final output stage of a high-bandwidth Arbitrary Waveform Generator (AWG) similar to what you have in the TIDA-00684 reference…
Part Number: TIDA-00684 Hello team,
In TIDA-00684 reference design, the schematic http://www.ti.com/lit/df/tidrov6/tidrov6.pdf calls for the use of CPLD, is that essential for the DAC38J84 JESD204B communication or can the DAC be communicated with directly…
Hi SK,
You can take a look at TIDA-00684 High-Bandwidth Arbitrary Waveform Generator Reference Design: DC or AC coupled, High-Voltage output that uses the DAC38J82 (2.5GSPS). We also have the DAC37J82 (1.6GSPS) and DAC39J82 (2.8GSPS) in the same family…
Hi Tamir,
The reason I suggested using a fully differential amplifier is because they have a VOCM pin that allows you set the common mode of the output signal.
For a suggested circuit I would recommend you look at the High-Bandwidth Arbitrary…
Part Number: THS3217 Other Parts Discussed in Thread: DAC3484 , , TIDA-00684
Hello,
I'd like to get proper circuit for DAC3484 and THS3217. I'm studying datasheet and TIDA-00684 but couldn't get correct circuit yet.
DAC3484 Output: Differential…
After digging into this further, I found the following function generator reference designs on ti.com here:

These three reference designs seem particularly relevant…
The THS3217/3215 were designed to simplify the DAC to amplifier interface. I wrote the datasheets, but apparently not clear enough
The buffers can handle quite a range of input common mode and generate only the differental output in the D2S output …
Hello Seema, Yes, if you have an AC coupled requirement a balun is best with your DC offset brought into the centertap on the secondary. If you need DC coupled output, LMH6702 is a good solution. I would note that for best HD suppression, you need to…
