MAX6612, MAX6612MXK pdf datash

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 (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.
