Variable Output Voltage
Hi, I need to design a circuit that can output different voltage outputs(variable, say from 3v to 10v) based on certain TTL inputs from a microprocessor. The circuit should be low output impedance. I was thinking of using a digital potentiometer connected to a voltage source and using microcontroller to control its resistance. I don't know if this is a good design because the output impedance varies(isn't it??).
