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.

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.

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 V DD = 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.
