LM393 is a dual differential comparator that operates from a single or dual power supply. It has a wide operating voltage range, input common-mode voltage includes ground, low power consumption, and low input bias current.
The LM393 is a dual differential comparator designed for single‑or dual‑supply operation over a wide voltage range. It features low supply current, low input bias current, and TTL/DTL/CMOS‑compatible outputs.
The document lists absolute maximum ratings, detailed electrical characteristics, typical performance curves, and ordering numbers for various package types (DIP‑8, SOP‑8, TSSOP‑8). It also includes pin descriptions and a block diagram of the internal architecture.
| Supply voltage range | 2 V ~ 36 V (or +1 V ~ +18 V) |
|---|---|
| Low supply current | 0.8 mA (typical) |
| Input bias current | 25 nA (typical) |
| Power dissipation | 570 mW |
| Operating temperature range | -40 °C ~ +70 °C |
The LM393 can operate from 2 V to 36 V (or from +1 V to +18 V) depending on the supply configuration.
The typical input bias current is 25 nA.
The device can dissipate up to 570 mW.
