MICROCHIP TECHNOLOGY MCP4921-E/P MCP4921 Series 1 Ch 12-Bit Voltage Output Digital-to-Analog Converter-PDIP-8 - 5 item(s)

can they all welcome to part two of our three-part tutorial on my who knows SPL interface today we're going to take a look at using microchips MCP for 922 digital to analog converter or DAC for short if you haven't seen part one of this series I would suggest watching that first as it covers the basics in terminology of SPI in more detail and will help you understand this video a little easier okay why add digital to analog converter and what does it do as computers including microcontrollers are based on a digital system they can only output a logic level high or a logical low voltage in the case of most art we knows this is 5 volt logic high and 0 volts or ground for logic low be very careful though because some microcontrollers including the arduino duo have logic level high of 3.3 volts whilst this is very useful for digital components sometimes we need to output a voltage that isn'
