Hi Mohamed,
Regarding the minimum GBW of the 4th stage:
The minimum GBW calculation used by FilterPro is the same for the Sallen-Key and MFB typologies. The GBW is calculated from: GBW = Ao x Q x fn x 100, where Ao is the gain of the stage (V/V),…
Hi Nathan,
Thank you for your post. If I narrow down our portfolio to 36V quad-channel precision amplifiers offered in a PDIP, we only have 9 parts:
OPA4277
OPA4131
LT1014D
LT1014
OPA404
TLE2024A
OPA4228
OPA4227
OPA4241
If you…
Hello K.N.,
Thank you for bringing the error to our attention. The same error is in place for the entire family; OPA227, OPA228, OPA2227, OPA2228, OPA4227, and OPA4228.

Hi Mike,
the NCV33274 is a very fast bipolar OPAmp with 24MHz bandwidth and 10V/µs slew rate. The LM2904 has 1.2MHz bandwidth and 0.5V/µs slew rate. So, when bandwidth and slew rate is an issue in your application then the LM2904 is a rather bad choice…
Amalinda,
The NA556 and OPA4228 Symbols and Footprints can be found in the product folders:

Other Parts Discussed in Thread: OPA4228 Dear all,
One of my cusotmer use OPA4228 to measure current shunt drop out voltage. since there is only one 12V is avaialble, i suggest the customer change the reference voltage to 6V. however, i failed to get…
Other Parts Discussed in Thread: INA106 , OPA4228 , INA105 , OPA277
I am working on a Impedance Meter for frequencies below 1 KHz and i already have all the circuits working for the voltage generation, voltage sense, reference potentials, data acquisition…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.
