Hi, I was wondering if the circuit below will be able to drive a 0.2 W speaker? [image] The capacitor is used to remove the DC offset from the PWM output, and the voltage divider is used to reduce the vpp to 1 V. The 10 kOhm resistor is to reduce current to the OPAMP, and 20 kOHM is to multply t…

Is this an appropriate circuit to drive my 8 ohm speaker using PWM?

Would feedback cause the output to compensate for deadzone problem?
