Hi team,
While reading through ADS1119's datasheet I found this.
While equating Eq.10 with Eq.11 to get Eq.12, I think there is a problem with the math. If my observation is correct the Gain parameter in Eq.12 should be in denominator (after Vref cancelled on both sides). That is,
RThermistor / (RThermistor + RREF ) = (Code / 215) x (1 / Gain)
Then the final equation will be
RThermistor = (RREF x Code) /[( 215 x Gain) - Code]
Please look into this .
Thank you,
Vineeth N
