Product Summary
The HA17903APS is a dual comparator. The HA17903APS is comparator designed for general purpose, especially for power control systems. The HA17903APS operates 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 singlevoltage power supply operation. The HA17903APS has 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.
