Part Number: LMH6619 Thermal resistance junction-to-ambient of LMH6619MA is given in datasheet. What are the thermal resistances junction-to-case and junction-to-board ?
Hi Yong,
the LMH6619 is a HF-OPAmp and is not designed to work with such high ohmic feedback resistances. When you have a look into the datasheet you will notice that the feedback resistance in all schematics is below 3kOhm.

According to datasheet, the Ibais and Voffset are different in the low and high input voltage ranges. it is not written what is the input voltage value for that change.

My customer try to use 2ch of LMH6619 as fully differential amplifer.
(1)Please teach reccomended circuit when input signal is about 10MHz and point to notice.( like fig12 in…
Thanks Michael,
Seems like I had set the lower temp range too low at -55 for the parametric search. I agree the OPA2810 seems like the best alternative in this case, some other dual channel alternatives are the LMH6612 & LMH6619 ( although slew rate…
Part Number: OPA2365-Q1 Other Parts Discussed in Thread: LMH6619-Q1 , OPA2365 Hi Team,
The OPA2365-Q1 datasheet lists Vs=5.5V as the test condition for some of the electrical specs. However, 5.5V is both the max recommended voltage and abs max of the…
Hi Lucy,
1. If the THS4222 chip operates at a high temperature of 60 degrees, then it could be that the part is oscillating. Have you looked at the THS4222 output to see if there is an oscillating sine wave?
2. It is possible that the large pick…
Hello Douglas,
I think what your experiment / data shows is that the op amp input offset voltage can have either polarity (pos or neg). When you apply the negative supply to the VEE pin, you see that some devices outputs swing below ground, whilst single…
