com 19-2219; Rev 0; 2/02 Thermistor-to-Digital Converter General Description The MAX6682 converts an external thermistor’s temperature-dependent resistance directly into digital form.
The thermistor and an external fixed resistor form a voltage-divider that is driven by the MAX6682’s internal voltage reference.
The MAX6682 measures the voltage across the external resistor and produces a 10-bit + sign output code dependent on that voltage.
The MAX6682 does not linearize the highly nonlinear transfer function of a typical negative temperature coefficient (NTC) thermistor, but it does provide linear output data over limited temperature ranges when used with an external resisto...
