General Description
●The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. 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. These comparators also have a unique characteris tic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.
●Features
●■ Wide supply
● — Voltage range: 2.0V to 36V
● — Single or dual supplies: ±1.0V to ±18V
●■ Very low supply current drain (0.4 mA) — independent of supply voltage
●■ Low input biasing current: 25 nA
●■ Low input offset current: ±5 nA
●■ Maximum offset voltage: ±3 mV
●■ Input common-mode voltage range includes ground
●■ Differential input voltage range equal to the power supply voltage
●■ Low output saturation voltage,: 250 mV at 4 mA
●■ Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems
●■ Available in the 8-Bump (12 mil) micro SMD package
●■ See AN-1112 for micro SMD considerations
●Advantages
●■ High precision comparators
●■ Reduced VOS drift over temperature
●■ Eliminates need for dual supplies
●■ Allows sensing near ground
●■ Compatible with all forms of logic
●■ Power drain suitable for battery operation
