Hello Andrew,
Thanks for reuploading the images. I agree with the statements you made and that the vias correspond to GND and +VS.
In regards to the GND via of C2 it's not clear to me why it was done in this way. It seems to make sense to tap to the…
Part Number: LMH730316 Other Parts Discussed in Thread: LMH730216 Hi,
Is it possible to get a copy of the board design files or at least the gerbers for the LMH730316 eval board?
Thanks,

Hi Lisa,
You are way ahead of me. Sorry. I had not noticed that the metric and imperial sizes are different!!
These components look to be either 1806 imperial (4.5mm x 1.6mm) or 1206 (3.2mm x 1.6mm). I think either one would fit the footprint. I'm…
Hello Wendy,
We have two blank EVM boards which support LMH6703. The customer can populate these with LMH6703 samples (one EVM is for D, one is for DBV package):

Part Number: LMH6703 Other Parts Discussed in Thread: LMH730216 , LMH730316 Hi Team,
We would like to ask for your assistance to the customer's inquiry below.
I ordered the LMH730216 Evaluation PCB. With RG=RF=560 ohms, I have about 4 dB of overshoot…
Hi BR,
You can buy a high speed sot-23 evaluation board here, www.ti.com/.../lmh730316 , and populate it with an LMH6629 configured for this high gain. Does this resolve your issue?
Best regards,
Sean
Other Parts Discussed in Thread: LMH730316 , LMH6702 , LMH730227 , LMH730216 , LMH6629 Hello,
Is LMH6702(SOT23 PKG) datasheet specification tested with LMH730316? At the customer evaluating of LM6702(SOT-23) with LMH730227, the distortion data is worse…
Hello Paul,
I'm not very familiar with OPA355 and the possible overshoot causes, so I won't make any comments. However, you should be able to use the SOT23 EVAL from other high speed amplifiers (e.g. LMH6629, etc.) for this device. The Enable pin may…
Hi Natan,
I will try and respond to the questions you had raised:
1) Noise: You are correct about the noise increase. But, I think there are workarounds for that. I wanted to see if limiting the AC impedance of the non-inverting input will quell your…
Hello Vladimir,
I've made some input impedance measurements for the LMV7219 (Vs=5V):
Rin = 750kohm
Calculated by measuring the input 1kHz sine wave amplitude drop / voltage division through a 93kohm series input resistance
Cin= 2.3pF…
