LP365

LP265 LP365 Micropower Programmable Quad Comparator December 1994 LP265 LP365 Micropower Programmable Quad Comparator General Description The LP365 consists of four independent voltage comparators The comparators can be programmed four at the same time for various supply currents input currents response times and output current drives This is accomplished by connecting a single resistor between the VCC and ISET pins These comparators can be operated from split power supplies or from a single power supply over a wide range of voltages The input can sense signals at ground level even with single supply operation The unique output NPN transistor stages are uncommitted to either power supply They can be connected directly to various logic system supplies so that they are highly flexible to interface with various logic families Application areas include battery power circuits threshold detectors zero crossing detectors simple serial A D converters VCO multivibrators voltage converters power sequencers and high performance V F converters and RTD linearization Features Y Y Y Y Y Y Y Single programming resistor to tailor power consumption input current speed and output current drive capability Wide single supply voltage range or dual supplies (4 VDC to 36 VDC or g 2 0 VDC to g 18 VDC) Low supply current drain (10 mA) and low power consumption (10 mW comparator) ISET e 0 5 mA VCC e 5VDC Uncommitted output stage selectable output levels Output directly compatible with DTL TTL C...
