4 / 20 page Absolute maximum ratings and operating conditions LM158W-LM258W-LM358W 4/20 2 Absolute maximum ratings and operating conditions Table 1. Absolute maximum ratings Symbol Parameter LM158W/AW LM258W/AW LM358W/AW Unit VCC Supply voltage +32 V Vi Input voltage -0.3 to VCC +0.3 V Vid Differential input voltage -0.3 to VCC +0.3 V Ptot Power dissipation (1) 1. Power dissipation must be considered to ensure maximum junction temperature (Tj) is not exceeded. 500 mW Output short-circuit duration (2) 2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is approximately 40 mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. Infinite Iin Input current (3) 3. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is driven negative. This is not destructive and normal output will be restored for input voltage higher than -0.3 V. 50 mA Toper Operating free-air temperature range -55 to +125 -40 to +105 0 to +70 °C Tstg Storage temperature range -65 to +150 °C Rthja Thermal resistance junction to ambient(4) (5) 4.

Human body model: 100 pF discharged through a 1.5 k Ω resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 2kV MM: machine model(7) 7. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating. 200 V CDM: charged device model(8) 8. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground. 1.5 kV |
