LM2901A

LM2901/ LM2901A/ LM2903/ LM2903A DUAL AND QUAD DIFFERENTIAL COMPARATORS Description The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset voltage specification. They are designed to operate from a single power supply over a wide range of voltages; however operation from split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage. The LM2901/2903 series comparators are designed to directly interface with TTL and CMOS. When operating from both plus and minus power supplies, the LM2901/2903 series comparators will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. The dual devices are available in SO-8, TSSOP-8, and MSOP-8, and the quad devices available in SO-14 and TSSOP-14 with industry standard pinouts. Both use green mold compound as standard. Features Wide Power Supply Range:  Single Supply: 2V to 36V  Dual Supplies: ±1.0V to ±18V Very Low Supply Current Drain—Independent of Supply Voltage  LM2903: 0.6mA  LM2901: 0.9mA Low Input Bias Current: 25nA Low Input Offset Current: ±5nA Typical Offset Voltage:  Non-A Device: 2mV  A Device: 1mV Common-Mode Input Voltage Range Includes Ground Differential Input Voltage Range Equal to the Power Supply Voltage Low Output Saturation Voltage:  LM2903: 200mV at 4mA  LM2901: 100mV at 4mA Output Voltage Compat...
