DESCRIPTION
The DS60 Micro-Centigrade Temperature Sensor is a factory-calibrated voltage output Centigrade
temperature sensor. The thermometer output has a typical sensitivity of +6.25mV/°C and a DC offset of
+424 mV. The measurement range is -40°C to +125°C, corresponding to a typical output range of +174
mV to +1205 mV. Because the output voltage is positive for the entire temperature range, there is no need
for a negative power supply. The accuracy of the analog output, taking into account amplifier
nonlinearity, gain variations, and temperature sensor variations is ±2.0°C from 0°C to 85°C and within
±3.0°C over the full voltage and temperature range.
The power supply range of the DS60 is 2.7V to 5.5V. Its low current requirement of 125 µA and wide
supply range make it ideal in battery-powered applications. To further reduce power dissipation, the
DS60 can be switched to a zero power standby state by logic gate outputs capable of sourcing current of
this magnitude.
The small size of the SOT-23 package, wide power supply range, and ultra-low power dissipation allow
the DS60 to be used in thermal management applications that are currently limited to nonlinear
thermistors. These include battery packs, LCD displays, disk drives, power supplies, and appliances.

This is a stress rating 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. For specific reliability information on this product, please
contact the factory in Dallas at (972) 371–4448.

NOTES:
1. All voltages are referenced to ground, unless otherwise specified.
2. Solder according to IPC standards.
3. Specified for VO sourcing 1.0 µA (max).
4. Thermometer error (expressed in °C) is the difference between [VO(T) - 424]/6.25 and the DS60 case
temperature at VDD = 3.0V, thus taking into account sensor error, DC offset error, sensor amplifier
gain variations, and amplifier nonlinearity.
5. Nonlinearity is the maximum deviation of an ideal linear slope for a given DS60.
6. This is the typical drift following 3 consecutive passes through a vapor phase.
