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 power supply 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.
