Max. Slew rate of 3 op-amp INSAMP

[Anonymous]

Hello Forum,

       

What is the max. operating freq. of 3 op-amp instrumentation amplifier user module in PSoC 1 ? Does the use of an SC block (for conversion gain, as they call it) reduce speed of the incoming pulse ?

       

Any working code which has only the 3 op-amp instrumentation amplifier with settings that would enable it to operate at very high slew rate would be very helpful.

The large signal response, slew rate, in the datasheet for the module, given

   

for 3.3 V and 5 V operation.

       

There is no small signal info in datasheet, 2 possibilities -

       

1) The CT blocks show in device datasheet a response with GBW specs. You could

   

back into this making broad assumption its a single pole response.

       

2) The module datasheet has settling time specs, if we assume dominant pole response

   

you could solve for GBW from settling time spec.
