HA17901A Series
Quadruple Comparators
REJ03D0806-0100 Rev.1.00 Mar 10, 2006
Description
The HA17901A 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.
Features
Wide power-supply
voltage range : 2 to 36 V Very low supply current : 0.8 mA Typ. Low input bias current : 25 nA Typ. Low input offset current : 5 nA Typ. Low input offset
voltage : 2 mV Typ. The common-mode input
voltage range includes ground Output
voltages compatible with
CMOS logic systems
