+ + + + + + LM2901/ LM2901A/ LM2903/ LM2903A DUAL AND QUAD DIFFERENTIAL COMPARATORS Description Pin Assignments The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset (Top View) voltage specification. They are designed to operate from a single power supply over a wide range of voltages however operation from 1OUT 1 8 VCC split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage. 2 7 1IN- - 2OUT 1 3 - 6 1IN+ 2IN- The LM2901/2903 series comparators are designed to directly 2 GND 4 5 2IN+ 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 SO-8/TSSOP-8/MSOP-8 distinct advantage over standard comparators. LM2903/ LM2903A 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 (Top View) standard pinouts. Both use green mold compound as standard. 1OUT 1 14 3OUT 2 13 2OUT 4OUT Features 3 12 GND VCC Wide Power Supply Range: 4 11 4IN+ 2IN- - Single Supply: 2V to 36V 2 4 Dual Supplies: 1.0V to 18V - 4IN- 2IN+ 5 10 Very Low Supply Current DrainIndependent of Supply Voltage 1IN- - 9 3IN+ 6 1 3 LM2903: 0.6mA - 1IN+ 7 8 3IN- LM2901: 0.9mA Low Input Bias Current: 25nA SO-14/TSSOP-14 Low Input Offset Current: 5nA LM2901/ LM2901A 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 Compatible with TTL, MOS and CMOS Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
