Part Number: OPA683 Other Parts Discussed in Thread: OPA684 I have been doing some TINA spice simulations with both the OPA683 and OPA684.
The non-inverting input is connected to ground, and the inverting input is connected to a small signal input and…
Part Number: OPA684 I am using the OPA684 with Vs= +3.3V and Vs- = -3.3V . I cannot find the Voh and Vol for the \DISABLE pin using those supply voltages.
Part Number: OPA4684 Other Parts Discussed in Thread: OPA684 Hi TI Team,
I see references to a SPICE model for your OPA4684 Quad Opamp ( and the OPA684 Single Opamp ) rmentioned on your Web site and on the various TI forums relating to these device…
Part Number: OPA4684 Other Parts Discussed in Thread: OPA684 Hi,
I've been looking for a replacement high speed op-amp ( as ADI have discontinued a part ).
I stumbled on your OPA4684 / OPA684 CFB op-amps, which look promising. However, while looking…
If you want perfect flatness at a gain of 100 through 1MHz, one option is the OPA684 - we did that with closed loop input stage CFA to really extend the gain range on a low power CFA, not FET input of course, but here you go, broadband,
and then just…
Part Number: OPA691 Other Parts Discussed in Thread: OPA684 1. The datasheet of OPA691 mentions the optimum value of feedback resistance that ensure reasonably good stability and bandwidth.
The specs mentioned are for ± 5V rail. Will it hold good for…
I attached a TINA file with the op amp models in them.
You only require 68V/usec slew rate, and a gain of 20V/V,
look at the OPA684 for a +/-5V low power solution.
While the inverting summer is standard, and item 6 above notes the BW for each channel will be the GBP/NG approximately for VFA implementation.
One of the interesting benefits of a low power current feedback implementation if the DC precision is not…
You are correct, but since these groups are always doing devices for the next rounds of test equipment they always have to do better than anything you can buy. In HD work, source cancellation methods are normally used, one of the very few published references…
You do realize the CLC401 has been out of production since about 2002 when the Lucent fab Shut down. Not sure about the A version, usually that is just a graded input offset voltage at final test, same die.
The CLC401 was one of the very few higher…
