Part Number: OPA820

Hallo,

I can not verify the Noninverting Pulse Response in our applikation.

VCC=6.2V...10V, VSS=-2V, Gain=+1, Pulse Signal High Level 4.6V, Pulse Signal Low Level 1V

Load: 50R series resistor+50R input resistance oscilloscop

Testboard TI DEM-OPA-SOT-1A

C1, M1, M2, M3: Output OPA820 for different VCC Values

C2: Input OPA820 (Generator)

Is the measured rising edge slew rate correct?

Regards
