NJM2901 SINGLE-SUPPLY QUAD COMPARATOR ■ GENERAL DESCRIPTION These devices offer higher frequency operation and faster switching than can be had from internally compensated quad op amps.Indeed for single-supply applications,the Darlington PNP input stage allows them to compare voltages that include ground.The two-stage common-emitter output circuit provides gain and output sink capacity of 6mA at an output level of 400mV.The output collector is left open,permitting the designer to drive devices.

NJM2901 SINGLE-SUPPLY QUAD COMPARATOR ■ GENERAL DESCRIPTION These devices offer higher frequency operation and faster switching than can be had from internally compensated quad op amps.Indeed for single-supply applications,the Darlington PNP input stage allows them to compare voltages that include ground.The two-stage common-emitter output circuit provides gain and output sink capacity of 6mA at an output level of 400mV.The output collector is left open,permitting the designer to drive devices in the range of 2V to 36V. ■ FEATURES ● Operating Voltage ● Single Supply Operation ● Open Collector Output ● Package Outline ● Bipolar Technology ( +2V~+36V ) DIP14, DMP14, SSOP14 ■ PIN CONFIGURATION (Top View) DIP14, DMP14, SSOP14 PIN FUNCTION 1.
