ABSOLUTE MAXIMUM RATINGS (Ta=25 )
LINEAR INTEGRATED CIRCUIT
PARAMETER SYMBOL RATINGS UNIT Supply Voltage V+ +20 V VI(DIFF) Differential Input Voltage +20 V Input Voltage VIN -0.3 to +20 (note 3) V Power Dissipation PD 200 mV Junction Temperature TJ +125 C Operating Temperature TOPR -40~ +85 C Storage Temperature TSTG -40~+150 C Note 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. The device is guaranteed to meet performance specification within 0 ~+70 operating temperature range and assured by design from -40 ~+85 . 3. When the supply voltage is less than +20V, the absolute maximum input voltage is equal to the supply voltage
