http://www.edn.com/design/analog/4337128/Make-a-DAC-with-a-microcontroller-s-PWM-timer Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM si…
Few microcontrollers include a DAC. Although you can easily find an inexpensive DAC to control from your microcontroller, you can use unused peripherals instead of adding parts. Fortunately, you can convert a microcontroller's ADC channel along with…

[TI博客大赛][原创]LM3S811之基于PWM的DAC http://bbs.ednchina.com/BLOG_ARTICLE_3005301.HTM http://www.fpga4fun.com/PWM_DAC_3.html One-bit DAC Take one pin of an FPGA, connect a speaker and listen to an MP3? Easy. Here, we'll use a PC to decode an MP3, and then s…
how to generate an analog output from a in-built pwm of Atmega 32AVR microcontrloller? you need a resistor, a capacitor and an opamp. opamp is not really necessary when you are driving a mosfet, but will make life a bit easier. just be aware, that th…
