The MAX6607/MAX6608 analog output temperature
sensors’ output voltage is a linear function of its die
temperature. The slope of the output voltage is
10mV/°C, and there is a 500mV offset at 0°C to allow
measurement of negative temperatures. The maximum
supply current is 15µA, and the supply voltage range is
from +1.8V to +3.6V for the -20°C to +85°C tempera-
ture range.
The temperature-to-voltage transfer function has an
approximately linear positive slope and can be
described by the equation:
where T is the die temperature of the MAX6607/
MAX6608 in °C.
Therefore:

FUNCTION
Temperature sensor ICs like the MAX6607/MAX6608
that sense their own die temperatures must be mount-
ed on, or close to, the object whose temperature they
are intended to measure. Because there is a good ther-
mal path between the package’s metal leads and the
IC die, the MAX6607/MAX6608 can accurately measure
the temperature of the circuit board to which it is sol-
dered. If the sensor is intended to measure the tempera-
ture of a heat-generating component on the circuit board,
it should be mounted as close as possible to that compo-
nent and should share supply and ground traces (if they
are not noisy) with that component where possible. This
maximizes the heat transfer from the component to the
sensor.
The thermal path between the plastic package and the
die is not as good as the path through the leads, so the
MAX6607/MAX6608, like all temperature sensors in plas-
tic packages, are less sensitive to the temperature of the
surrounding air than they are to the temperature of their
leads. They can be successfully used to sense ambient
temperature if the circuit board is designed to track the
ambient temperature.
As with any IC, the wiring and circuits must be kept insu-
lated and dry to avoid leakage and corrosion, especially if
the part is operated at cold temperatures where conden-
sation can occur.
The error introduced by the part self-heating is negligible.
