LM2903WYPT STMicroelectronics

LM2903W Low-power, dual-voltage comparator Datasheet production data 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) D SO-8 Low input bias current: 25 nA typ. (Plastic micropackage) 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 P supply voltage TSSOP8 TTL, DTL, ECL, MOS, CMOS compatible (Thin shrink small outline package) outputs ESD internal protection: 2 kV Pin connections (top view) Description 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. The input common-mode voltage range includes negative rail even though operated from a single power supply voltage. 1 - Output 1 All pins are protected against electrostatic 2 - Inverting input 1 discharge up to 2 kV. Consequently, the input 3 - Non-inverting input 1 + - voltages must not exceed the V or V - CC CC 4 - V CC magnitudes. 5 - Non-inverting input 2 6 - Inverting input 2 7 - Output 2 + 8 - V CC November 2012 Doc ID 022662 Rev 2 1/15 This is information on a product in full production. www.st.com 15Contents LM2903W Contents 1 Schematic diagram 3 2 Absolute maximum ratings and operating conditions . 4 3 Electrical characteristics . 5 4 Typical application schematics 7 5 Package information 10 5.1 SO-8 package information 11 5.2 TSSOP8 package information . 12 6 Ordering information . 13 7 Revision history . 14 2/15 Doc ID 022662 Rev 2
