Well there are quite a number of dual CFA's in the THS, OPA, and LMH lines,
OPA2694 is really fast, but not as much output drive,
OPA2684, is slower, but hold more constant BW over gain
etc, etc,
Update from the customer:
Restarting does not help but I think it has something to do with the parts I use. Right now I just ran the simulation three times and it runs with valid outputs. However if I change the op-amp in the post amplifier circuit it…
Other Parts Discussed in Thread: OPA684 , OPA2684 , LMV7239 , LMV7291 , TINA-TI , LMV7271 Hi E2E,
My customer is simulating the OPA2684 and the OPA684 in TINA. The sim works fine until he imports the LMV7239 comparator. Once imported, TINA fails to find an…
Other Parts Discussed in Thread: OPA2684 Hi E2E,
My customer has a circuit consisting of 2 stages of amplifiers (OPA2684 I believe) going into a CR filter, series diode, then RC filter. He gets an output of 1.4V when he runs the simulation.
He then copies…

So, just to be sure, the output swing can be same as specifications show (for gain of +5) in a gain of -1 application, right? Because there obviously the input common mode range is not an issue (as long as it is in 0 to 3.8V w/ 5V…
Hi Peter,
The OPA684 should fit your need quite nicely. In order to achieve 100V/V with 100MHz bandwidth, you might want to consider using 2 amplifiers in series each with a maximum gain of 10V/V.
Note that the gain resistor will need to be change as…
