4 / 20 page Absolute maximum ratings LM224A-LM324A 4/20 2 Absolute maximum ratings Table 1. Absolute maximum ratings Symbol Parameter LM224A LM324A Unit VCC Supply voltage ±16 or 32 V Vi Input voltage -0.3 to VCC + 0.3 V Vid Differential input voltage (1) 1. Neither of the input voltages must exceed the magnitude of VCC + or V CC -. 32 V Ptot Power dissipation: N suffix D suffix 500 400 500 400 mW Output short-circuit duration (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 will set up again for input voltage higher than -0.3 V. 50 mA Toper Operating free-air temperature range -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): SO14 TSSOP14 DIP14 4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short- circuits on all amplifiers. These are typical values given for a single layer board (except for TSSOP which is a two-layer board). 103 100 83 °C/W Rthjc Thermal resistance junction to case: SO14 TSSOP14 DIP14 31 32 33 °C/W ESD HBM: human body model(5) 5. Human body model, 100 pF discharged through a 1.5 k Ω resistor into pin of device. 700 V MM: machine model(6) 6. Machine model ESD, a 200 pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5 Ω), into pin-to-pin of device. 150 CDM: charged device model 1500 |
