# LMx93, LM2903 Dual Differential Comparators## Features ️· Single-Supply or Dual Supplies
️· Wide Range of Supply Voltage (2V to 36V)
️· Low Supply-Current Drain (0.4 mA Typical per Comparator)
️· Low Input Bias Current (25 nA Typical)
️· Low Input Offset Current (3 nA Typical - LM139)
️· Low Input Offset Voltage (2 mV Typical)
️· Common-Mode Input Voltage Range Includes Ground
️· Differential Input Voltage Range Equal to Maximum-Rated Supply Voltage (±36V)
️· Low Output Saturation Voltage
️· Output Compatible With TTL, MOS, and CMOS
## DescriptionThese devices consist of two independent voltage comparators designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies is possible. Current drain is independent of the supply voltage. Outputs can be connected for wired-AND relationships.
