1 / 18 page LM2901/ LM2901A/ LM2903/ LM2903A Document number: DS36779 Rev. 3 - 2 1 of 18 www.diodes.com May 2016 © Diodes Incorporated 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, 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 Compatible with TTL, MOS and CMOS Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments (Top View) 1 2 3 7 6 5 4 8 SO-8/TSSOP-8/MSOP-8 1OUT VCC 2IN- 2IN+ 1IN- 1IN+ GND 2OUT 1 - - 2 LM2903/ LM2903A (Top View) 1 2 3 13 12 11 4 14 SO-14/TSSOP-14 1OUT 3OUT GND 7 6 5 9 10 8 4IN+ 3IN- 3IN+ 4IN- 2OUT VCC 2IN- 2IN+ 1IN- 1IN+ 4OUT 2 - 1 - - 4 - 3 LM2901/ LM2901A Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony- free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds. |
