4 / 20 page Absolute maximum ratings LM158-LM258-LM358 4/20 2 Absolute maximum ratings Table 1. Absolute maximum ratings Symbol Parameter LM158,A LM258,A LM358,A Unit VCC Supply voltage +/-16 or 32 V Vi Input voltage 32 V Vid Differential input voltage 32 V Ptot Power dissipation (1) 1. Power dissipation must be considered to ensure that the maximum junction temperature (Tj) is not exceeded. 500 mW Output short-circuit duation (2) 2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15 V. 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 is restored for input voltages above -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 Tj Maximum junction temperature 150 °C Rthja Thermal resistance junction to ambient(4) (5) SO-8 MiniSO-8 TSSOP8 DIP-8 4.

Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k Ω resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 300 V MM: machine model(7) 7. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations while the other pins are floating. 200 V CDM: charged device model(8) 8. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 1.5 kV |
