I am wanting to output 3000 hz at 7 vac 1 amp. I have found info for the digital wave form generator that makes a very stable 3khz at 5 volts, what do I need to make this at exactly 7 volts A/C output? The voltage and frequency are fixed and have to be very stable, .5% or less error. I am not wanting pots for trim, digital input buttons for voltage and frequency. Is the system capable of reading frequency and voltage and self regulating?

Reference design;-

  • 3000 Hz Sine wave with module AD9850
  • Power output 10w with TDA2003
  • Voltage control by MCP41010 single-channel digital potentiometer
  • RMS Voltage measure by AD736

BTW, what do you try to do? drive ac motor?
