7.3.2.2 Output Voltage Linearity

As illustrated in Figure 6-2, the ISOTMP35 device exhibit a linear output of 10 mV/°C. Use Equation 2 to calculate the output voltage.

Equation 1. VOUT = (TA - TINFL) ✕ TC + VOFFS

where

  • VOUT is the ISOTMP35 voltage output for a given temperature
  • TA is the ambient temperature in°C
  • TINFL is the temperature inflection point for a piecewise segment in°C
  • TC is the ISOTMP35 temperature coefficient or gain
  • VOFFS is the ISOTMP35 voltage offset
