Thank you all for your support! I have a much better understanding on the topic now.
I've tried different configurations both with the THS3217 or an op-amp. The most satisfying one (at least considering the simulations) is the following one, using OPA694…
Part Number: OPA858 Other Parts Discussed in Thread: OPA694 , , OPA855 Dear Team: My customer use OPA694 and OPA858 in LiDAR application, but they're looking for something better performance OPA.
I want to know, whether TI has some main recommende…
Hello Michael-san,
Thank you for your comment.
I understand THS3491, OPA694/5, LMH6703 can be alternative part for THS3201.
Comparison table is also helpful!
Thanks and best regards,
Ryo Akashi

Hi Sean,
The more I look at this, the more I am inclined to think that one of these plots is wrong. As an example of what we should expect, take a look at the specs for the OPA694 and OPA2694, two op-amps that are also identical except that one is single…
Other Parts Discussed in Thread: OPA694 Hi,
In datasheet of opa694, input offset voltage is stated as 0.5mV. In attachment, I shared a simple inverting amplifier by using spice model of opa694. When I applied 0V input voltage, I got 200mV output offset…
Part Number: LMH6624 Other Parts Discussed in Thread: OPA843 , OPA694 , THS4271 , OPA659 We use an opamp to scale the DAC's output into a suitable voltage range. We're looking at using the LMH6624 at a gain of 3x. Apparently, there are some tricks…
Hello Jay,
For the OPA694 (current feedback type), your feedback resistor (R23 + R25= 250ohm) seems too low. According to OPA694 Figure 39 (Feedback resistor vs. Noise Gain), you may want to raise the feedback to ~420ohm (Noise Gain = 2V/V in your case…
