CMOS Micro-Power Comparator plus Voltage Follower
The MC14578 is an analog building block consisting of a very-high input impedance comparator.
The voltage follower allows monitoring the noninverting input of the comparator without loading.
Four enhancement-mode MOSFETs are also included on chip.
These FETs can be externally configured as open-drain or totem-pole outputs.
The drains have on-chip static-protecting diodes.
Therefore, the output voltage must be maintained between VSS and VDD.
The chip requires one external component.
A 3.
9 MΩ ±10% resistor must be connected from the Rbias pin to VDD.
This circu...
