Almost on-topic, because it's for an ambedded app.
Does anyone have a favorite method for conversion of a pulse and direction PWM signal to a bipolar analogue signal? I can do the obvious opamp approach, but I'm hoping that someone knows of a nice small IC that only needs a resistor and a capacitor, in a SOT-23 package, or even better 8 channels in a 30-pin SOIC??
Well, anything small will do :-)
Cheers
