The output O voltage characteristic is factory-calibrated for a typical sensitivity of +6.25mV/C and a DC offset of +424mV at 0C. Its operating temperature range is -40C to +125C, corresponding to an output voltage range of +174mV to +1205mV. The DS60 has 2.0C accuracy over a 0C to +85C temperature range and over the full +2.7V to +5.5V power supply range. Its accuracy is within 3.0C 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 DS60s 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 125A, which allows the DS60 to be switched to a zero power standby state when the gate is forced to a logic 0. 1 of 2 100906 V O DS60 ABSOLUTE MAXIMUM RATINGS* Voltage on V GND -0.3V to +6.5V DD Output Current 5.0mA Operating Temperature Range -40C to +125C Storage Temperature Range -55C to +150C ESD Susceptibility (Human Body Model) 2kV Soldering Temperature 215C for 60s (Vapor Phase) 220C for 15s (IR) * 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.
