MAX6612MXK

High-Slope, Low-Power, Analog Temperature Sensor in an SC70 Package


Please check latest availability status for a specific part variant.

Description

The MAX6612 is a low-power precision analog output temperature sensor in a tiny 5-pin SC70 package. The sensitivity of the output voltage to temperature is a high 19.53mV/°C. This sensitivity provides superior noise immunity. The voltage/temperature slope is chosen to provide convenient bit weights when the MAX6612 drives the input of an ADC with a 2.5V or 5V reference.

The MAX6612 provides an analog voltage output proportional to temperature. Accuracy is ±1.2°C (max) at +25°C, ±3.0°C (max) from TA = 0°C to +70°C, and ±5.5°C (max) from TA = -10°C to +125°C. Useful measurements can be obtained at temperatures as high as +150°C. Self-heating effects are negligible due to the low current consumption of the part.

Unlike many analog temperature sensors, the MAX6612 is stable with large capacitive loads. Any capacitive load greater than or equal to 1000pF yields stable operation, providing broad flexibility in board-level design.

The operating temperature range varies with the supply voltage, with a higher supply voltage enabling a wider temperature range. The MAX6612 can be used over a range of -10°C to +125°C with a supply voltage of 3.3V or greater. For applications with a supply voltage of 2.4V, the MAX6612 can be used over a temperature range of -10°C to +70°C.
