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 Waveform…
Hello Fred,
I was looking into other products; it does seem like the LM7171 is the only one that fits all your specifications you have listed. If you would be able to go with another package other than the DIP option; there are about 60 devices that…
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: Differ…
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 (rejecting…
Part Number: DAC5681 Other Parts Discussed in Thread: THS3215 , THS3491 , THS3217 , THS3091 , TIDA-00684 We are in the designing phase of a zero-IF based transmitter using DAC5681 with THS3215.
Our required output frequency range is from 1MHz to 50 MHz.

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…
