General 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 dri-

ves the input of an ADC with a 2.5V or 5V reference.

The MAX6612 provides an analog voltage output propor-

tional to temperature. Accuracy is ±1.2°C (max) at +25°C,

±3.0 (max) from T

= 0°C to +70°C, and ±5.5°C (max)

from T

= -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 oper-

ation, 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.
