CA3098 Datasheet (Intersil) - Programmable Schmitt Trigger with Memory / Dual Input Precision Level Detector

CA3098, Programmable Schmitt Trigger with Memory / Dual Input Precision Level Detector

of Circuit Operation 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).

This condition is maintained until the signal input voltage rises to or exce

The CA3098 can be operated with either a single power supply with maximum operating voltage of 16V, or

CA3098 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 cir
