LM393, LM293, LM193, LM2903 Dual Differential Comparators 1 Features 3 Description
• Single-Supply or Dual Supplies These devices consist of two independent voltage 1 comparators that are designed to operate from a • Wide Range of Supply Voltage single power supply over a wide range of voltages. – Maximum Rating: 2 V to 36 V Operation from dual supplies also is possible as long – Tested to 30 V: Non-V Devices as the difference between the two supplies is 2 V to 36 V, and V – Tested to 32 V: V-Suffix Devices CC is at least 1.5 V more positive than the input common-mode voltage. Current drain is • Low Supply-Current Drain Independent of Supply independent of the supply voltage. The outputs can Voltage: 0.4 mA (Typical) Per Comparator be connected to other open-collector outputs to • Low Input Bias Current: 25 nA (Typical) achieve wired-AND relationships. • Low Input Offset Current: 3 nA (Typical) (LM193) The LM193 device is characterized for operation from • Low Input Offset Voltage: 2 mV (Typical) −55°C to +125°C. The LM293 and LM293A devices are characterized for operation from −25°C to +85°C. • Common-Mode Input Voltage Range The LM393 and LM393A devices are characterized Includes Ground for operation from 0°C to 70°C. The LM2903, • Differential Input Voltage Range Equal to LM2903V, and LM2903AV devices are characterized Maximum-Rated Supply Voltage: ±36 V for operation from −40°C to +125°C. • Low Output Saturation Voltage
