Low-Voltage Analog Temperature Sensor in an SC70 Package

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.

The MAX6613 provides an analog voltage output proportional to temperature. Accuracy is ±4.0°C (max) over a range of TA = 0°C to +50°C and ±4.4°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 -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 temperature range.
