Low-Voltage Analog Temperature
Sensor in an SC70 Package
General Description
The MAX6613 is a low-power analog precision analog
output temperature sensor in a tiny 5-pin SC70 pack-
age. The MAX6613 operates over a supply voltage
range of 1.8V to 5.5V, with a typical current consump-
tion of only 7.5µA. It is particularly well suited for
portable applications where minimizing battery cost
and maximizing useful battery life are crucial.
The MAX6613 provides an analog voltage output pro-
portional to temperature. Accuracy is ±1.3°C (max)
over a range of TA = 0°C to +50°C and ±2.0°C (max)
from TA = -20°C to +80°C. Self-heating effects are neg-
ligible due to the low current consumption of the part.
Unlike many analog temperature sensors, the MAX6613
is stable with any capacitive load from 0pF to 1000pF,
providing broad flexibility in board-level design.
The operating temperature range varies with the volt-
age supply. The MAX6613 can be used over a range of
-55°C to +130°C with a supply voltage of 2.5V to 5.5V.
For applications with a supply voltage of 1.8V, the
MAX6613 can be used over a temperature range of
+25°C to +130°C.

Low-Voltage Analog Temperature
Sensor in an SC70 Package
Applications Information
Sensing Circuit Board and
Ambient Temperature
A temperature sensor IC like the MAX6613 that senses
its own die temperature must be mounted on, or close
to, the object whose temperature it is intended to mea-
sure. Because there is a good thermal path between
the package’s metal lead and the IC die, the MAX6613
can accurately measure the temperature of the circuit
board to which it is soldered. If the sensor is intended
to measure the temperature of a heat-generating com-
ponent on the circuit board, it should be mounted as
close as possible to that component and should share
supply and ground traces (if they are not noisy) with
that component where possible. This optimizes the
thermal connection 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 lead, so the
MAX6613, like all temperature sensors in plastic pack-
ages, is less sensitive to the temperature of the sur-
rounding air than to the temperature of its leads. It can
be successfully used to sense ambient temperature if
the circuit board is designed to track the ambient tem-
perature.
As with any IC, the wiring and circuits must be kept
insulated and dry to avoid leakage and corrosion,
especially if the part is operated at cold temperatures
where condensation can occur.
The change in die temperature introduced by the part
due to self-heating is negligible.
