Description
When the signal input voltage of the CA3098 is equal to or less than the “low” reference voltage (LR), current flows from an external power supply through a load connected to Terminal 3 (“sink” output).
Features
- (see Block Diagram): 1. Differential amplifiers and summer: the circuit uses two differential amplifiers, one to compare the input voltage with the “high” reference, and the other to compare the input with the “low” reference. The resultant output of the differential amplifiers actuates a summer circuit which delivers a trigger that initiates a change in state of a flipflop. 2. Flip-flop: the flip-flop functions as a bistable “memory” element that changes state in response to each trigger comman.
