LM193 - Low power dual voltage comparator

General Description

The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mV max.

for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages.

Key Features

  • Figure 1. Pin Configuration.
  • Wide single supply voltage range 2.0VDC to 36VDC or dual supplies ±1.0VDC, to ±18VDC.
  • Very low supply current drain (0.8mA) independent of supply voltage (2.0mW/comparator at 5.0VDC).

Philips Semiconductors Product specification Low power dual voltage comparator LM193/A/293/A/393/A/2903 DESCRIPTION The LM193 series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mV 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 characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The LM193 series was designed to directly interface with TTL and CMOS.
