LM293 from STMicroelectronics is a low-power dual voltage comparator.

The LM293 from STMicroelectronics is a low-power dual voltage comparator. Here are its specifications, descriptions, and features:

Specifications:

  • Supply Voltage Range: 2V to 36V (single supply) or ±1V to ±18V (dual supply).
  • Low Supply Current: 0.4mA (typical) per comparator, independent of supply voltage.
  • Low Input Bias Current: 25nA (typical).
  • Low Input Offset Current: 5nA (typical).
  • Input Offset Voltage: 2mV (typical), 5mV (maximum).
  • Common-Mode Input Voltage Range: Includes ground (0V).
  • Differential Input Voltage Range: Equal to the supply voltage.
  • Output Voltage Swing: Compatible with TTL, CMOS, and MOS logic levels.
  • Output Sink Current: 6mA (minimum).
  • Operating Temperature Range: -40°C to +125°C.

Descriptions:

  • The LM293 is a dual independent precision voltage comparator designed for single or split-supply operation.
  • It features low input offset voltage and bias current, making it suitable for precision applications.
  • The device is optimized for wide voltage ranges and low power consumption.

Features:

  • Wide Supply Voltage Range: Operates from 2V to 36V.
  • Low Power Consumption: Ideal for battery-powered applications.
  • ESD Protection: Improved immunity to electrostatic discharge.
  • Open-Collector Output: Allows flexible output configurations.
  • High Accuracy: Low input offset voltage and bias current.
  • Industrial Temperature Range: Suitable for harsh environments.

The LM293 is commonly used in voltage monitoring, level shifting, and signal conditioning applications.
