EL2018 General Description

The EL2018 represents a quantum leap forward in comparator speed, accuracy and functionality.

Manufactured with Elantec's 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. The three-state output stage is designed to be TTL compatible for any power supply combination, yet it draws a constant current and does not generate glitches. When the output is disabled, the supply current consumption drops by 50%, but the input stage and latch remain active.

Elantec facilities comply with MIL-I-45208A and other applicable quality specifications. For information on Elantec's processing, see QRA1: Elantec's Processing-Monolithic Products.
