LM393 is a dual differential comparator manufactured by Texas Instruments (TI).

The LM393 is a dual differential comparator manufactured by Texas Instruments (TI).

Specifications:

  • Supply Voltage Range: 2V to 36V (single supply) or ±1V to ±18V (dual supply)
  • Low Supply Current: 0.4mA (typical) per comparator
  • Low Input Bias Current: 25nA (typical)
  • Low Input Offset Current: 5nA (typical)
  • Low Input Offset Voltage: 2mV (typical)
  • Common-Mode Input Voltage Range: Includes ground
  • Differential Input Voltage Range: Equal to the supply voltage
  • Output Voltage Swing: Compatible with TTL, CMOS, and MOS logic
  • Operating Temperature Range: -40°C to +125°C

Descriptions:

The LM393 consists of two independent precision voltage comparators designed to operate from a single power supply over a wide voltage range. It features low input offset voltage and low supply current, making it suitable for battery-powered applications.

Features:

  • Wide Single-Supply Voltage Range (2V to 36V)
  • Low Input Bias and Offset Currents
  • Low Output Saturation Voltage
  • TTL, DTL, ECL, MOS, and CMOS Compatible Outputs
  • ESD Clamps on Inputs Increase Ruggedness
  • Available in Multiple Package Options (SOIC, PDIP, TSSOP, etc.)

The LM393 is commonly used in voltage monitoring, level detection, and analog-to-digital conversion applications.
