Microchip PIC16F15323 has a 5-bit DAC.
The reason I use a PWM DAC is to keep the cost down.Since you plan a uC in the scheme I would think about just using a DAC like the MCP4725 or similar. A small footprint in a 6 pin package using I2C. VSS, VDD, A0 (Address) and Vout.

Well alrighty then.The reason I use a PWM DAC is to keep the cost down.
I am afraid this is the part that I need more reading on. I don't have a lot of knowledge of transformers.How much of a load is on the transformer? You will need to drive the transformer sufficiently based on the load. What peak to peak voltage do you want? Also, for transformer make sure you have no DC offset. I think after you send it through the LPF you will need to send it also through a HPF with cutoff of say 10Hz so the transformer does not see any DC offset, which will driver more current into the transformer. What is the DC resistance of the transformer?
Looks like the perfect little chip for my application, even have a NCO if I need to match the frequency as precise as possible. Thanks for the recommendation.Microchip PIC16F15323 has a 5-bit DAC.
