MAX6613 Low-Power, Precision Analog-Output Temperature Sensor

The MAX6613 is a low-power, precision analog-output temperature sensor in a compact 5-pin SC70 package. The MAX6613 operates over a 1.8V to 5.5V supply voltage range and consumes only 7.5µA typical current. The MAX6613 is ideal for portable applications that require low battery cost and the most efficient use of battery life.

The MAX6613 provides an analog voltage output proportional to temperature. Accuracy is ±4.0°C (max) for TA ₌ 0°C to +50°C and ±4.4°C (max) for _TA = -20°C to +80°C. Because the device consumes very little current, self-heating effects are negligible. Unlike many analog temperature sensors, the MAX6613 is stable with any capacitive load from 0pF to 1000pF, providing great flexibility in board-level design. The operating temperature range of the MAX6613 varies with the supply voltage. The MAX6613 operates over the -55°C to +130°C temperature range with a 2.5V to 5.5V supply voltage and over the +25°C to +130°C temperature range with a 1.8V supply voltage.
