Digital to analog data conversion
The digital to analog conversion to benifit to data signal processing .and all most the project apply the data conversion to used many project such TEMP SENSOR,CLOSE LOOP CONTROL,MEASURE MENT and direction measure etc. in the experiment like this will show you about how to connect microcontroler to LTC1661(linear tech nology company) this cuitcuit show the diagram,source code,shcmatics the equation change hexcadicimal to volttage can be test by multimeter measure voltage change So
if we want 5 volt solve flow equation
1.
Vout=(Data/1024) * Vref ;
Data= data digital;
1024= 10 bit resolution;
Vref = Vcc ;
// 0 = channel 0;
// 0x100=100hex
// can be calculate by equation
// vout = (data/1024)*5v(Vref)
// data = 0x100 change to decimal = 256 ;
// Vout = (256/1024)*5v(Vref)
// Vout = 1.25 volt
and then you can read the data sheet LTC1661 also
