概览

LM393 系列为双独立精确电压比较器，能够实现单个或分离电源运行。此类器件允许单电源运行下的共模范围扩展至接地水平。此器件的输入偏移电压规格低至 2.0 mV，因此成为消费汽车和工业电子元件中很多应用的绝佳选择。

  • Wide Single-Supply Range: 2.0 Vdc to 36 Vdc
  • Split-Supply Range: +/-1.0 Vdc to +/-18 Vdc
  • Very Low Current Drain Independent of Supply Voltage: 0.4 mA
  • Low Input Bias Current: 25 nA
  • Low Input Offset Current: 5.0 nA
  • Low Input Offset Voltage: 2.0 mV (max) LM393A 5.0 mV (max) LM293/393
  • Input Common Mode Range to Ground Level
  • Differential Input Voltage Range Equal to Power Supply Voltage
  • Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS Logic Levels
  • ESD Clamps on the Inputs Increase the Ruggedness of the Device without Affecting Performance

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
