Anyone? Frank ----- Original Message ----- From: "Frank J. Soria" To: Sent: Friday, January 31, 2003 11:35 PM Subject: [PIC] PWM signal to 4v min - 7.5v max output I am sure this is very very simple circuit. I need to convert a PWM signal from a PIC to create a +4v to +7.5V DC control voltage. I am limited to a 8v 0.5a max power supply. I have been reading that i need a low pass filter and an op amp. But I really need specific parts and a circuit digram. And basic description on how it all works would help greatly. thanks, Frank -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
