Absolute Maximum Ratings 1/
Supply Voltage (VCC) ......................................................... ±18V dc
Differential Input Voltage 2/............................................... ±1V dc
Differential Input Current 2/............................................... ±25mA
Input Voltage ...................................................................... Supply voltage
Output Short Circuit Duration ............................................ Continuous
Storage Temperature Range................................................ -65°C to +150°C
Lead Temperature (soldering, 60 seconds)......................... +300°C
Power Dissipation (PD) ....................................................... 500mW
Maximum Junction Temperature (TJ)................................. +150°C
Ambient Operating Temperature Range............................. -55°C to +125°C
Absolute Maximum Ratings Notes:
1/ Stresses above the absolute maximum rating may cause permanent damage to
the device. Extended operation at the maximum levels may degrade
performance and affect reliability.
2/ The inputs are protected by back-to-back diodes. Current limiting resistors are
not used in order to achieve low noise performance. If the differential input
voltage exceeds ±1V, the input current should be limited to ±25mA.
