SN8P2740 Series
ADC, OP-amp, Comparator 8-Bit Micro-Controller
Comparator 0 compares positive terminal‟s voltage and negative terminal‟s voltage, and then output result to output pin.
When V+ > V-, comparator outputs high status. When V+ < V-, comparator outputs low status. Comparator output
terminal builds in delay control block to achieve output hysteresis to filter output transition condition. The delay option
has 16-step including no delay, 1/Fhosc, 2/Fhosc, 3/Fhosc, 4/Fhosc, 5/Fhosc, 6/Fhosc, 7/Fhosc, 8/Fhosc, 9/Fhosc,
10/Fhosc, 11/Fhosc, 12/Fhosc, 13/Fhosc, 14/Fhosc, 15/Fhosc controlled by CM0D[3:0] bits.
