ear positive slope and can be approximated by the
equation:
V OUT = 0.40V + (0.01953V/ ° C ? T ° C) - (2 ? 10 -6 ? T ° C 2 )
where T is the MAX6612 ’ s die temperature in ° C.
Therefore:
T ( ° C) = (V OUT - 0.40V) / 0.01953V/ ° C
Applications Information
Detailed Description
The MAX6612 is an analog output temperature sensor
whose output voltage is a linear function of its die tem-
perature. The slope of the output voltage is 19.53mV/ ° C
and there is a 400mV offset at 0 ° C to allow measure-
ment of negative temperatures. The maximum supply
current is 35μA, and the supply voltage range is from
2.4V to 5.5V for the -10 ° C to +150 ° C temperature
range. The temperature error is less than ±1.2 ° C at T A
= +25 ° C, ±3 ° C from T A = 0 ° C to +70 ° C, and ±4.5 ° C
from T A = -10 ° C to +125 ° C.
The operating temperature range varies with the supply
voltage with higher supply voltages enabling wider
temperature ranges. The MAX6612 can be used over a
range of -10 ° C to +125 ° C with a supply voltage of 3.3V
or greater. For applications with a supply voltage of
2.4V, the MAX6612 can be used over a temperature
range of -10 ° C to +70 ° C.
Sensing Circuit Board and
Ambient Temperatures
Temperature sensor ICs like the MAX6612 that sense
their own die temperatures must be mounted on or
close to the object whose temperature they are intend-
ed to measure. Because there is a good thermal path
between the SC70 package ’ s metal leads and the IC
die, the MAX6612 can accurately measure the temper-
ature of the circuit board to which it is soldered. If the
sensor is intended to measure the temperature 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.
