Rainbow Electronics MAX6613 User Manual
General Description
The MAX6613 is a low-power analog precision analog
output temperature sensor in a tiny 5-pin SC70 package. The MAX6613 operates over a supply voltage
range of 1.8V to 5.5V, 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.
The MAX6613 provides an analog voltage output proportional 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 negligible 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 voltage 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.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
