GENERAL DESCRIPTION

The LND393 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators. They are specifically designed to operate from a single power supply over a wide range of voltages. In addition, the comparators have the unique ability in that the input common-mode voltage range includes ground, while operated from a single power supply voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

FEATURES

? Wide supply (Voltage range single and dual supplies 5V to 30V, ±2.5V to ±15V)

? Very Low supply current drain(0.8mA)

? Low input biasing current(25nA)

? Low input offset voltage(±5nA)

? Maximum offset voltage(±5mV)

? Input common-mode voltage range includes ground

? Differential input voltage range equal to the power supply voltage

? Output voltage compatible with TTL, DTL,ECL ,MOS and CMOS logic systems

ADVANTAGES

? High precision comparators
