LM2903HYPT

LM2903H 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) Low input bias current: 25 nA typ. Low input offset current: ±5 nA typ. Input common-mode voltage range includes ground Low output saturation voltage: 250 mV typ. (IO = 4 mA) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs SO8 TSSOP8 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. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. 1 = Output 1 2 = Inverting input 1 3 = Non-inverting input 1 4 = VCC5 = Non-inverting input 2 6 = Inverting input 2 7 = Output 2 8 = VCC+ October 2015 DocID9875 Rev 6 This is information on a product in full production. 1/12 www.st.com Contents LM2903H Contents 1 Absolute maximum ratings and operating conditions ................. 3 2 Circuit schematics........................................................................... 4 3 4 Electrical characteristics ................................................................ 5 Package information ....................................................................... 7 5 6 2/12 4.1 SO8 package information .................................................................. 8 4.2 TSSOP8 package information ........................................................... 9 Ordering information..................................................................... 10 Revision history ............................................................................ 11 DocID9875 Rev 6 LM2903H 1 Absolute maximum ratings and operating conditions Absolute maximum ratings and operating conditions Table 1: Absolute maximum ratings (AMR) Symbol Parameter VCC Supply voltage Vid Differential input voltage Vin Input voltage Rthjc Tj Tstg ±36 V -0.3 to 36 (1) 20 Thermal resistance junction to ambient Thermal resistance junction to case SO8 125 TSSOP8 120 SO8 40 (2) (2) TSSOP8 Storage temperature range -65 to 150 (3) CDM: charged device model °C/W 160 °C 800 (4) MM: machine model mA 37 Maximum junction temperature HBM: human body model ESD Unit ±18 or 36 Output short-circuit to ground Rthja Value 200 (5) V 1500 Notes: (1) + Short-circuit from the output to VCC can cause excessive heating and eventual destruction. The maximum + output current is approximately 20 mA, independent of the magnitude of V CC . (2) Short-circuits can cause excessive heating and destructive dissipation. Values are typical. (3) Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. (4) Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. (5) Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins.

(2) The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so there is no load charge on the reference of input lines. (3) Positive excursions of the input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3 V (or 0.3 V below the negative power supply, if used). (4) (5) The response time specified is for a 100 mV input step with 5 mV overdrive. Maximum values are guaranteed by design and evaluation.
