Set the High Frequency Cutoff at the Amplifier’s Input.Set the Low Frequency Cutoff at the Feedback Loop. Set the Low Frequency Cutoff at the Amplifier’s Input.Find the Maximum Thermal Resistance of the Heat Sink.Convert the Total Power to a Transformer VA Rating.Find the Output Power from a Transformer’s Voltage Rating.Find the Maximum Supply Voltage Output by a Transformer.Find the Maximum Supply Voltage Needed by the Amplifier.Determine the Required Power Supply Voltage and Power.Since this is a rather long article, here are links to the different sections: This is an Excel spreadsheet that calculates output power, heat sink size, gain, and other useful parameters: It’s also good to have the Overture Design Guide. It also has schematics for bridged and parallel amplifier circuits: It has all of the performance specifications, absolute maximum ratings, schematics, and design tips:Īpplication note AN-1192 has additional information that fills in gaps left out of the datasheet. I highly recommend reading the datasheet before building your amplifier. I’ve also included the schematic and Gerber files for the power supply I used. BONUS: Download my parts list to see the components I used to get great sound quality from this amplifier.
