Hi Kawai-san,
For recommendation # 5 above, the LMH6502 total load will be 100ohm AC (=Rout + 50ohm_scope = 50ohm + 50ohm_scope = 100ohm). It won't be 50ohm as you have indicated as there is Rout in series with the 50ohm input of the scope.
Regards…
Hi Kawai-san,
To answer your questions:
Q1:What is the definition for V_DMAX ? Is it the differential voltage between IN+ and IN- ?
A1: Yes, VDMAX is the maximum input differential voltage (specified as +/- and not peak-to-peak). With low values…
Hello Vinit,
Some comments:
1. NA is the square of the total input referred voltage noise (with Rs in place but assumed noiseless). This includes the LMH6629 noise voltage, noise current flowing through the equivalent source resistance Rseq (25ohm…
Hi Athul,
For protection against short circuit condition, you may have to devise an external protection, as shown below. This circuit will limit the output current to ~83mA (=0.6V/ 7.1ohm) sourcing. It works by removing the input condition that causes…
Hi Elnur,
In order to help you with your question, could you please provide / attach the datasheet for the CCD sensor, and the current LM98725 register settings (it could be a text or Excel file) you are using?
If you cannot send the entire sensor…
Hi Marc,
On the internal ESD diodes, unfortunately there is no additional information available to my colleagues either. The only comment I got from them is that the diodes will have the nominal -2.5mV/ deg. C temperature coefficient on their On voltage…
Hi Axel and JC,
For DC waveforms: If the Vcc and Vee currents are DC (non-time-varying), you just multiply "V x I" (for both Vcc and the Vee pins) and you have the total power consumed by the OPA1632. You could use a heavy capacitor on the supplies…
Hello Ken and Seb,
I've put together a spreadsheet of the most promising devices for your review and consideration. This spreadsheet uses your conditions:
Cin= 80pF
Required Bandwidth > 10kHz (I've used 100kHz to allow margin)
Min / Max input…
Hello All,
I found the fab drawing on the LMH730033 EVAL board which I'm uploading for your information:

Hi Peter,
Just to clarify, the business case I had asked for was for information purposes so that one could justify the cost / expense of developing the Space version of the LMH6629. In other words, it would be used so that TI can make sure that your…
