Hi Team,
A customer would like to know if it is possible to amplify a 5V pulse of 6KHz to 100V pulse of 6KHz. Additional parameter below:
V+ =120V
V- =-5V.
Total power supply = +/-75V (or single supply of up to 150V.)
Will this circuit work in real time?
Thank you.
Regards,
Marvin
Hi Marvin,
The circuit should work.
The input of the squarewave's rise and fall edges are specified at 4usec. The slew rate of OPA455 is rated at 32 V/usec. So delta of 100V in gain can take up to 100/32 = 3.125 usec, and OPA455 should be able to keep up with the rising and falling time of the input signal.
OPA455 Squarewave 11092022.TSC
If you have additional questions, please let us know.
Best,
Raymond
Hi Marvin,
and the heat dissipated wihtin the OPA455 also looks well:
Follow the recommendations given in section 10 of datasheet, though.
