LM2901DR Texas Instruments 模拟比较器 Quad Diff Ind Temp

FEATURES DESCRIPTION

The LM2901EP consists of four independent

2• Wide Supply Voltage Range

precision voltage comparators with an offset voltage

• LM2901: 2 to 36 VDCor ±1 to ±18 VDC specification as low as 2 mV max for all four

• Very Low Supply Current Drain (0.8 mA) — comparators. These were designed specifically to

Independent of Supply Voltage operate from a single power supply over a wide range

of voltages. Operation from split power supplies is • Low Input Biasing Current: 25 nA

also possible and the low power supply current drain

• Low Input Offset Current: ±5 nA is independent of the magnitude of the power supply

• Offset Voltage: ±3 mV voltage. This comparator also has a unique

• Input Common-Mode Voltage Range Includes characteristic in that the input common-mode voltage

GND range includes ground, even though operated from a

single power supply voltage.

• Differential Input Voltage Range Equal to the

Power Supply Voltage Application areas include limit comparators, simple

analog to digital converters; pulse, squarewave and

• Low output saturation voltage: 250 mV at 4 mA time delay generators; wide range VCO; MOS clock

• Output Voltage Compatible with TTL, DTL, timers; multivibrators and high voltage digital logic

ECL, MOS and CMOS Logic Systems gates. The LM2901EP was designed to directly

interface with TTL and CMOS. When operated from

ADVANTAGES both plus and minus power supplies, it will directly

interface with MOS logic— where the low power drain

• High Precision Comparator of the LM2901EP is a distinct advantage over
