NJM2903/2403

SINGLE-SUPPLY DUAL COMPARATOR

■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE

The NJM2903/2403 consist of two independent precision voltage
comparators with an offset voltage specification as low as 5.0mV max
for two comparators, which were designed specifically to operate from a
single power supply over a wide range of voltages. Operation from split
power supplies is also possible and the low power supply current drain is NJM2903D/2403D NJM2903M/2403M
independent of the magnitude of the power supply voltage. The ( DIP8 ) ( DMP8 )
NJM2903/2403 have unique characteristic: the input common-mode
voltage range includes ground, even though operated from a single
power supply voltage. Application areas include limit comparators,
simple analog-to-digital converters; pulse, square-wave and time delay
generators; wide range VCO; MOS clock timers; multivibrators and high NJM2903V/2403V NJM2903L/2403L
voltage digital logic gates. The NJM2903/2403 were designed to directly ( SSOP8 ) ( SIP8 )
interface with TTL and MOS. When operated from both plus and minus
power supplies, the NJM2903/2403 will directly interface with MOS logic
where their low power drain is a distinct advantage over standard
comparators. NJM2903E NJM2903RB1
