SHUNT_VOLTAGE_REFERENCE_RESISTOR_CALCULATOR:
Shunt Voltage Reference External Resistor Quick Start Calculator

ACTIVE

Description

This external resistor quick-start calculator tool lets you easily calculate valid external resistor values relative to voltage reference, supply and load-current bounds. With these inputs, you can instantly view the resulting calculations and use the color-coded indications to understand whether the calculated outputs are valid or invalid.

Features
  • Case-specific tool to calculate external resistor value associated with shunt voltage reference
  • Input fields for: voltage reference, supply voltage, load current and Iq bound values
  • Real-time effects of input values on schematic
  • Quick indicators notifying user of valid and invalid outputs
  • Error messages
  • Embedded details in numerous cells for additional user guidance
  • Useful links included for further voltage reference support
