- See the LM2903H for similar devices with operating temperature up to 150°C.
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. In addition, the device has a unique
characteristic in that the input common-mode voltage range 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. (IO = 4 mA). - Differential input voltage range equal to the supply voltage.
- TTL, DTL, ECL, MOS, CMOS compatible outputs.
- Automotive qualification.
Absolute Maximum Ratings :
1. Short-circuits from the output to VCC+ can cause excessive heating and possible destruction. The maximum output current is approximately 20 mA, independent of the magnitude of VCC+.
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 k ohm resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are left 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 ohm ). This is done for all couples of connected pin combinations while the other pins are left 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.
