Draw and explain the interfacing of DAC to 8051.

1 Answer

Answer :

Diagram: 

image

* Microcontroller generates output which is in digital form but many controlling system requires analog signal as they don't accept digital data thus making it necessary to use DAC which converts digital data into equivalent analog voltage. 

* In the figure shown, we use 8-bit DAC 0808. This IC converts 8 bit digital data into equivalent analog current. Hence we require an I to V converter to convert this current into equivalent voltage.
