LM385DG4-1-2 Frequently Asked Questions (FAQs)

  • The typical output impedance of the LM385DG4-1.2 is around 0.2 ohms, which is relatively low and makes it suitable for applications where a stable voltage reference is required.
  • When the input voltage is below the minimum recommended value of 4.5V, the LM385DG4-1.2 may not function properly and the output voltage may not be regulated. It's recommended to ensure that the input voltage is within the specified range for proper operation.
  • While the LM385DG4-1.2 can provide a stable voltage reference, it's not designed to be used as a voltage regulator. It's intended for use as a voltage reference in applications such as analog-to-digital converters, digital-to-analog converters, and other precision voltage-sensitive circuits.
  • The output voltage of the LM385DG4-1.2 has a temperature coefficient of around 20 ppm/°C, which means that the output voltage will change by approximately 0.002% for every 1°C change in temperature. This is relatively low and makes the device suitable for applications where temperature stability is important.
  • The LM385DG4-1.2 is a commercial-grade device and may not be suitable for high-reliability or high-temperature applications. Texas Instruments offers other voltage reference devices that are specifically designed for high-reliability and high-temperature applications, such as the LM385M-1.2 or the LM4132-1.2.
