Analog Comparator
A/D Converter
The Analog Comparator is built around a high speed comparator and a CMOS output
buffer/voltage converter. Figure 3-20 shows the Analog Comparator block diagram. The
total propagation delay from the AIN0 and AIN1 pins to the internal ACO signal is typi-
cally 90ns, max 210ns. For parts, the total propagation delay from the AIN0 and AIN1
pins to the internal ACO signal is typically 500 ns, max 750 ns.
The comparator features an internal hysteresis of typical 1 mV, max 4 mV @ 25 ° C to
ensure clean switching.
