LTC2990IMS datasheet by Linear Technology

LTC2990IMS Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VIN pin?
  The maximum voltage that can be applied to the VIN pin is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I configure the LTC2990IMS for a specific voltage range?
  The LTC2990IMS has a programmable voltage range. You can configure it by connecting the VREF pin to a voltage divider network that sets the desired voltage range. The datasheet provides a formula to calculate the required resistor values.
• What is the accuracy of the voltage measurement?
  The LTC2990IMS has a typical accuracy of ±0.5% over the entire operating temperature range. However, this accuracy can be affected by the quality of the external resistors used for the voltage divider network.
• Can I use the LTC2990IMS to measure negative voltages?
  No, the LTC2990IMS is designed to measure positive voltages only. If you need to measure negative voltages, you'll need to use an external voltage translator or a different IC.
• How do I handle the case where the input voltage is higher than the maximum rating of the VIN pin?
  You can use an external voltage divider network or a voltage limiter circuit to reduce the input voltage to a level within the maximum rating of the VIN pin. Alternatively, you can use a voltage clamp circuit to protect the VIN pin from overvoltage conditions.
