Single-supply dual comparator

Japan Radio Corporation  

NJM2903/2403

SINGLE-SUPPLY DUAL COMPARATOR

■ GENERAL DESCRIPTION

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

independent of the magnitude of the power supply voltage. The

NJM2903/2403 has a 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 voltage digital logic gates. The

NJM2903/2403 were designed to directly 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.
