5 / 25 page ![]() LM158, LM258, LM358, LM158A, LM258A, LM358A Absolute maximum ratings DocID2163 Rev 15 5/25 3 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 -0.3 to 32 Vid Differential input voltage ±32 Output short-circuit duration (1) Infinite Iin Input current (2) 5 mA in DC or 50 mA in AC (duty cycle = 10 %, T = 1 s) mA Toper Operating free-air temperature range -55 to 125 -40 to 105 0 to 70 °C Tstg Storage temperature range -65 to 150 Tj Maximum junction temperature 150 Rthja Thermal resistance junction to ambient (3) SO8 125 °C/W MiniSO8 190 DFN8 2x2 57 TSSOP8 120 Rthjc Thermal resistance junction to case (3) SO8 40 MiniSO8 39 TSSOP8 37 ESD HBM: human body model (4) 300 V MM: machine model (5) 200 CDM: charged device model (6) 1.5 kV Notes: (1)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. (2)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 clamp. In addition to this diode action, there is 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. (3)Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values. (4)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. (5)Machine model: a 200 pF 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. (6)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. |
