The EL2018 represents a quantum leap forward in comparator speed, accuracy and functionality. Manufactured with Elantecs proprietary Complementary Bipolar process, this device uses fast PNP and NPN transistors in the signal path. A unique circuit design gives the inputs the ability to handle large common mode and differential mode signals, yet retain high speed and excellent accuracy. Careful design of the front end insures the part maintains speed and accuracy when operating with a mix of small and large signals.
