finally i've received schematic of test point that involves AD744
In addition, the major difference between ADA4817 and AD744 (the one used in the application note of Walt Jung) is that it uses different polarity of JFET (ADA4817: N-Channel and AD744:P-Channel). It means that the polarity of the Walt's…
Shown on right side of Figure 47 of AD549 datasheet is the bottom view of the amplifier. Below is the outline dimensions for AD744 and you can take this as reference, it has the same package as AD549.
Yes I agree,selection of op amp is not easy. You should be able to identify which parameters your application should be of most interest.It could be the noise, precision or the cost for example. If your going to choose between AD845 and AD744…
Please teach me AD215.
I would like to trim input offset.
Do you have a reference circuit?
I think that it uses Trim Pin of AD744 in Fig23.
But, in recent years, OPAMP with TrimPin is few.
I checked AD203SN data sheet.
Fig.20 and Fig21 are…
I can think of over 60 opamps with a 40V/usec slew and less than 0.5mV offset that run off 30V rails. I would also be looking for a low input bias current as a 200Hz filter needs large RC time constants, which you would probably want to generate…
