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.
