General Description
The MAX6682 converts an external thermistor’s temper-
ature-dependent resistance directly into digital form.
The thermistor and an external fixed resistor form a volt-
age-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 coef-
ficient (NTC) thermistor, but it does provide linear out-
put data over limited temperature ranges when used
with an external resistor of the correct value. Over the
0° to +50°C temperature range, the MAX6682 produces
output data that is scaled to 8LSBs/°C (for 0.125°C res-
olution), provided that the correct thermistor and exter-
nal resistor values are used. Other temperature ranges
can be easily accommodated, but do not necessarily
yield data scaled to an even number of LSBs per
degree.
The 3-wire SPI-compatible interface can be readily
connected to a variety of microcontrollers.
The MAX6682 is a read-only device, simplifying use in
systems where only temperature data is required.
Power-management circuitry reduces the average ther-
mistor current, minimizing self-heating. Between con-
versions, supply current is reduced to 21A (typ). The
internal voltage reference is shut down between mea-
surements.
The MAX6682 is available in a small, 8-pin MAX pack-
age and is specified over the -55°C to +125°C temper-
ature range.
