MAX6613
Low-Voltage Analog Temperature
Sensor in an SC70 Package
General Description
Benefits and Features
● Minimizes Power Consumption with Ultra-Low 7.5µA
The MAX6613 is a low-power precision analog output
temperature sensor in a tiny 5-pin SC70 package. The
MAX6613 operates over a 1.8V to 5.5V supply voltage
range, with a typical current consumption of only 7.5µA. It
is particularly well suited for portable applications where
minimizing battery cost and maximizing useful battery life
are crucial.
(typ) Supply Current
● Minimizes Board Space with Tiny SC70 Package
● Extends Performance Range with Wide 1.8V to 5.5V
Operating Range
● Ideal for Broad Range of Thermal Management
Applications
The MAX6613 provides an analog voltage output pro-
portional to temperature. Accuracy is ±4.0°C (max)
• -55°C to +130°C Measurement Range
• 4.0°C Accuracy
over a range of T = 0°C to +50°C and ±4.4°C (max)
A
from T = -20°C to +80°C. Self-heating effects are neg-
A
ligible due to the low current consumption of the part.
● Pin Compatible with LM20
Unlike many analog temperature sensors, the MAX6613
is stable with any capacitive load from 0pF to 1000pF,
providing broad flexibility in board-level design.
Ordering Information
PIN-
TOP
The operating temperature range varies with the volt-
age supply. The MAX6613 can be used over a -55°C to
+130°C range with a 2.5V to 5.5V supply voltage.
For applications with a supply voltage of 1.8V, the
MAX6613 can be used over a +25°C to +130°C tempera-
ture range.

Detailed Description
Sensors
The MAX6613 analog output temperature sensor’s out-
put voltage is a discrete function of its die temperature.
The maximum supply current is 13µA, and the supply
voltage range is from 2.5V to 5.5V for the -55°C to
+130°C temperature range, or 1.8V to 5.5V for the
+25°C to +130°C temperature range.
The MAX6613 can be used to replace temperature
sensors using other output algorithms. Table 1 provides
information for a linear and quadratic output equation.
Contact the factory for performance information about
another equation.
Transfer Function
The temperature-to-voltage transfer function is approx-
imately linear and can be described by the quadratic
equation:
2
V
OUT
= -0.0000022 5 T - 0.01105 × T + 1.8455V
In many cases, a linear approximation can be applied:
= -0.01123 × T + 1.8455V
V
OUT
where T is the die temperature of the MAX6613 in °C.
Therefore:
T = (1.8455 - V )/0.01123V

MAX6613
Low-Voltage Analog Temperature
Sensor in an SC70 Package
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.
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 component 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 change in die temperature introduced by the part due
to self-heating is negligible.
Chip Information
PROCESS: BiCMOS
Package Information
For the latest package outline information and land pat-
terns (footprints), go to www.maximintegrated.com/
packages. Note that a “+”, “#”, or “-” in the package code
indicates RoHS status only. Package drawings may show
a different suffix character, but the drawing pertains to the
package regardless of RoHS status.
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 packag-
es, is less sensitive to the temperature of the surrounding
air than to the temperature of its leads. It can be suc-
cessfully used to sense ambient temperature if the circuit
board is designed to track the ambient temperature.
