Unused devices must be stored in conductive material. Protect devices from static discharge and static fields. Stresses above those listed under Absolute Maximum Ratings may cause perma- nent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect device reliability. ABSOLUTE MAXIMUM RATINGS * Supply Voltage ............................................................ 15V Input Voltage, Any Terminal .............. – 1.0 to (VCC +0.3V) Operating Temperature (TC1023) ......... – 20 °C to +100°C Operating Temperature (TC1024) ......... – 20 °C to +125°C Storage Temperature ............................ – 55 °C to +150°C Lead Temperature (Soldering, 10 sec) ................. +300 °C NOTES: 1. VOUT outputs open circuited. 2. VOUT is 0V through approximately 100kΩ to ground when CE = VIH. 3. Recovery time is the period required for VOUT to rise from 0V (shutdown state) to the voltage corresponding to the measured temperature driving a 100pF capacitive load. 4. Accuracy = Difference between calculated output voltage (10mV/ °C x Device case temperature at specified temperature and power supply) and measured output voltage expressed in °C. 5. Nonlinearity = deviation of output voltage versus temperature from the best-fit straight line over the device rated temperature range. |
