#74195 - RE: Ramping instead of zero-crossing
Responding to: ???'s previous message
Attach a DAC or a smoothed (low-pass filtered?) PWM output to a triac and drive the voltage up slowly

added cost of DAC + its PCB space (and isolation of course)) as compared to a 6 pin MOC3061/MOC3081 ?? Is there any solid justification?
