STMicroelectronics LM193/LM193A/LM293/LM293A/LM393/LM393A Low Power Dual Voltage Comparators Datasheet
The LM193, LM193A, LM293, LM293A, LM393 and LM393A are low‑power dual‑voltage comparators that operate from a single supply ranging from +2 V to +36 V (or +1 V to +18 V) and feature very low supply current (0.4 mA typical at +5 V). They offer low input bias current (25 nA typ.), low input offset voltage (+‑1 mV typ.) and output saturation voltage of 250 mV typ.
The document includes order codes for each device, schematic diagrams, absolute maximum ratings, detailed electrical characteristics, typical application circuits, and a revision history. It is intended for designers needing precise performance data and part selection information.
