LM2903 Low-power dual voltage comparator Datasheet - production data Related products See the LM2903W for similar devices with higher ESD performances See the LM2903H for similar devices with 6 operating temperature up to 150 C 0LQL62 62 SODV WLF SODV WLF Description DFNDJH PLF RSU DFNDJH PLFUR S This device consists of two independent low- power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. 3 )1 PP SODV DFNDJHWLF PLFURS In addition, the device has a unique characteristic WKLQ VKULQN VPDOO in that the input common-mode voltage range RXWOLQFNDJH D H S includes the negative rail even though operated from a single power supply voltage. Features Wide single supply voltage range or dual supplies +2 V to +36 V or 1 V to 18 V Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at +5 V) Low input bias current: 25 nA typ. Low input offset current: 5 nA typ. Input common-mode voltage range includes negative rail Low output saturation voltage: 250 mV typ. (I = 4 mA) O Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs Automotive qualification September 2021 DocID2470 Rev 14 1/21 This is information on a product in full production. www.st.com 623 76Contents LM2903 Contents 1 Schematic diagram 3 2 Package pin connections . 4 3 Absolute maximum ratings and operating conditions . 5 4 Electrical characteristics . 6 5 Typical application schematics 8 6 Package information 11 6.1 SO8 package information . 12 6.2 TSSOP8 package information . 13 6.3 MiniSO8 package information . 14 6.4 DFN8 2x2 package mechanical data (LM2903Q2T) 15 6.5 DFN8 2x2 package mechanical data (LM2903YQ3T) . 17 7 Ordering information . 18 8 Revision history . 19 2/21 DocID2470 Rev 14
