While reading the MAX6605 datasheet, which is an analog temperature sensor, I ran across the following:
The temperature-to-voltage transfer function has an approximately linear positive slope and can be described by the equation:
VOUT = 744mV + (T ✕ 11.9mV/°C)
where T is the MAX6605’s die temperature in °C. Therefore:
T (°C) = (VOUT - 744mV) / 11.9mV/°C
To account for the small amount of curvature in the transfer function, use the equation below to obtain a more accurate temperature reading:
VOUT = 0.744V + 0.0119V/°C ✕ T(°C) + 1.604 ✕ 10^-6 V/°C^2 ✕ (T(°C))^2
My algebra is terrible. How do I solve for T(°C) from the last equation?
