林CMOS双差分比较仪 LIN CMOS DUAL DIFFERENTIAL COMPARATORS

description

This device is fabricated using LinCMOS technology and consists of two independent voltage comparators, each designed to operate from a single power supply. Operation from dual supplies is also possible if the difference between the two supplies is 2 V to 18 V. Each device features extremely high input impedance typically greater than 1012Ω, allowing direct interfacing with high-impedance sources. The outputs are n-channel open-drain configurations and can be connected to achieve positive-logic wired-AND elationships.
