| Simple Power Question | 31 Mar 2009 23:48 GMT | 14 |
Ok, I have a full wave rectifier (with no smoothing) fed to a resistor
of value 1 ohm. The sine wave has amplitude 1 volt. What is the
average power delivered to the load?
Now is the average power defined as Vav^2/R = (2/pi)^2=0.407W

Anyone know of an integrated 8 bit DAC/filter/amp? 250mW ish for the amp
would be fine. I'm looking to upgrade an existing design that uses a couple
of max part+ TDA7052.

I need to recharge a capacitor (strobe-like application). Once
capacitor voltage reaches ~230V the converter turns off (open loop
operation).
