7.3.1 LM50-Q1 and LM50HV-Q1Transfer Function

The LM50-Q1 and LM50HV-Q1 follow a simple linear transfer function to achieve the accuracy as listed in the Section 6.5 and Section 6.6 tables.

Use Equation 1 to calculate the value of VO.

Equation 1. VO = 10mV/°C × T °C + 500mV

where

  • T is the temperature in °C
  • VO is the LM50-Q1 and LM50HV-Q1 output voltage
