Low Power Low Offset Voltage Dual Comparator LM2903P8 Low Power Low Offset Voltage Dual Comparator General Description The LM2903P8 consist of two independent precision voltage comparators with a typical offset voltage of 1.0mV and high gain. The LM2903P8 are specifically designed to operate from a single power supply over wide range of voltages. Operation from split power supply is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. DIP-8 The LM2903P8 is available in standard packages of DIP-8. Features Wide supply voltage range -Single supply: 2.0V to 36V -Dual supplies: ±1.0V to ±18V Low supply current drain: 0.6mA Low input bias current: 25nA (typical) Low input offset current: ±5.0nA (typical) Low input offset voltage: 1.0mV (typical) Input common mode voltage range includes ground Differential input voltage equals to the power supply voltage Low output saturation voltage: 200mV at 4mA Open collector output RoHS compliant and halogen free Applications Battery Charger Cordless Telephone Switching Power Supply DC-DC Module PC Motherboard Communication Equipment TAITRON COMPONENTS INCORPORATED www.taitroncomponents.com Tel: Fax: (800)-TAITRON (800)-824-8766 (800)-TAITFAX (800)-824-8329 (661)-257-6060 (661)-257-6415 Rev.

Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to “Absolute Maximum Ratings” for extended period may affect device reliability. 2. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3 VDC (at 25°C). 3. ESD is tested according to MIL-STD-883D Method 3015.7 Class 1 for ESD-HBM and JEDEC EIA/JESD22-A115 Class A for ESD-MM.

Limits over the full temperature are guaranteed by design, but not tested in production. 5. The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at 25°C). The upper end of the common-mode voltage range is VCC-1.5V (at 25°C), but either or both inputs can go to +36V without damages, independent of the magnitude of the VCC. Rev.
