FUNCTIONAL DESCRIPTION
1. Mode 1
This mode sets the DO pin to “L” and stops conversion upon completion of conversion of 12 bits. To restart
conversion, set CS to “H” once then to “L”. In this mode, converted data is output from the MSB.
Timing diagram
2. Mode 2
This mode continues conversion until CS becomes “H” after it becomes “L”. Converted data is output from the
LSB, with the first piece of converted data output 20 clock cycles after CS becomes “L”. Changing the channel
select pin settings before starting sampling of one analog input allows another to be converted.
