TEMPERATURE CONVERSION
The direct-to-digital temperature sensor measures temperature through the use of an on-chip temperature
measurement technique with an operating range from -40°C to +95°C. Temperature conversions are
initiated upon power-up, and the most recent result is stored in address locations E2h and E3h, which are
updated every 10ms. Temperature conversion will not occur during an active read or write to memory.
The value of each resistor is determined by the temperature-addressed look-up table that assigns a unique
value to each resistor for every 2°C increment with a 1°C hysteresis at a temperature transition over the
operating temperature range. This can be seen in Figure 2.
