Low-Voltage Analog Temperature
Sensor in an SC70 Package
Table 1. Linear and Quadratic Output Equation
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 temperature-to-voltage transfer function is approxi-
mately linear and can be described by the quadratic
equation:
In many cases, a linear approximation can be applied:

where T is the die temperature of the MAX6613 in °C.
Therefore:
The MAX6613 can be used to replace temperature sen-
sors using other output algorithms. Table 1 provides
information for a linear and quadratic output equation.
