Hi Ramakrishna,
Achieving 30dBm output power within 1MHz to 50MHz frequency range would be tough using just the THS3215. You will have to cascade output of the THS3215 with THS3491 in-order to get 30dBm output power into 50-ohm load.
You may want…
Hello Elisha,
The interstage network is intended to be pretty flexible including the idea of adding image reject filters right there. Often the high speed dacs are specified with a 50ohm at their outputs to ground (for current sourcing DACs) and the…
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…
Check out THS3217 Diff-amp. This is a high bandwidth, high signal swing device. Reference TI Design TIDA-00684 which showcases a DAC with diff-amp application. The TI Design is centered on the DAC38J84 but that output interface is very similar to the…
Jingtai,
Not that I know of. Can you use an amplifier in your design? If so, take a look at the TSW3080EVM reference design for an example. A TI design using this product can be found at the following link:

Part Number: THS3217 Other Parts Discussed in Thread: THS3091 , THS3491 Team,
Please help to answer on customer query on previous e2e thread - https://e2e.ti.com/support/data-converters/f/73/t/839127

Hi Rohit,
We thank for…
Yes, you can always use the standard filtering techniques on the output. Ferrite beads, etc. should go after the diode and output cap and be placed on the power plane as it is routed to the load.
Any buck converter can be used as an inverter, though…
Hi Jingtai,
This TI design is from precision data converter group it show how to convert unipolar output of the DAC to bipolar.
However if you want to use high speed DAC with high output voltage swing, please refer to following ti designs.

Part Number: THS3091 Other Parts Discussed in Thread: TIDA-00684 I intend to use two THS3091 in a current sharing arrangement, operating from +/-15V to generate signals of up to 20Vpk-pk on 100Ohm (10Vpk-pk after 50 Ohm termination). Ideally I would like…
Hello Oliver, The THS3217 is another potential option. This device was built specifically as line driver for current output DACs. There is also a reference design for an Arbitrary Waveform Generator using the DAC38J84, THS3217 and THS3091. A link to the…
