Maxim MAX66120K-000AA+

13,56 МГцЧтение/запись-25°C ~ 50°C

Overview

The MAX66120K-000AA+ 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 MAX66120K-000AA+ drives the input of an ADC with a 2.5V or 5V reference. The MAX66120K-000AA+ 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 MAX66120K-000AA+ 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 MAX66120K-000AA+ 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 MAX66120K-000AA+ can be used over a temperature range of -10°C to +70°C.
