DESCRIPTION
The DS60 analog temperature sensor measures its own temperature and provides these measurements to
the user in the form of an output voltage (V
O
) that is proportional to degrees centigrade. The output
voltage characteristic is factory-calibrated for a typical sensitivity of +6.25mV/°C and a DC offset of
+424mV at 0°C. Its operating temperature range is -40°C to +125°C, corresponding to an output voltage
range of +174mV to +1205mV. The DS60 has ±2.0°C accuracy over a 0°C to +85°C temperature range
and over the full +2.7V to +5.5V power supply range. Its accuracy is within ±3.0°C over the operating
temperature range and full supply range. Because the output voltage is positive for the entire temperature
range, there is no need for a negative power supply.
The DS60’s tiny size, low-current operation, and wide supply range make it ideal for use in battery-
powered applications. To further reduce power dissipation, the DS60 can be powered by any logic gate

output that is capable of sourcing 125µA, which allows the DS60 to be switched to a zero power standby
state when the gate is forced to a logic 0.

These are stress ratings only and functional operation of the device at these or any other conditions
above those indicated in the operation sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods of time may affect reliability.
The Dallas Semiconductor DS60 is built to the highest quality standards and manufactured for long-term
reliability. All Dallas Semiconductor devices are made using the same quality materials and
manufacturing methods. However, the DS60 is not exposed to environmental stresses, such as burn-in,
that some industrial applications require.
