The LM393 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.
Voltage range: 2.0V to 36V
single or dual supplies: ±1.0V to±18V
Maximum offse tvoltage: ±9mV
Package include:
20pcs*LM393
