Part Number: OPA2675
Tool/software:
I am trying to simulate the said op amp in Tina TI with an RC filter and PWM. The results do not look consistent. At 100pct duty cycle (20KHz 3.3V) i get the required Vout but it takes 200 us to get anything above 1.1V. At 50pct duty cycle the Vout remains at 1.1V. From the graphs it seems that my RC filter works fine but the amplifier does not amplify the signal unless im at 100pct duty cycle. Is there anything wrong with my simulation?
