Description
The HA17903A series products are comparators designed for general purpose, especially for power control systems.
These ICs operate from a single power-supply
voltage over a wide range of
voltages, and feature a reduced powersupply current since the supply current is independent of the supply
voltage.
These comparators have the merit which ground is included in the common-mode input
voltage range at a single
voltage power supply operation. These products have a wide range of applications, including limit comparators, simple A/D converters, pulse/square-wave/time delay generators, wide range VCO circuits, MOS clock timers, multivibrators, and high-
voltage logic gates.
