4 / 22 page Absolute maximum ratings and operating conditions LM2904 4/22 2 Absolute maximum ratings and operating conditions Table 1. Absolute maximum ratings (AMR) Symbol Parameter Value Unit VCC Supply voltage (1) 1. All voltage values, except differential voltage are with respect to network ground terminal. ±16 or 32 V Vid Differential input voltage(2) 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. ±32 V Vin Input voltage -0.3 to 32 V Output short-circuit duration (3) 3. 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 s Iin Input current (4) 4. 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 diodes 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 duration than 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 +125 °C Tstg Storage temperature range -65 to +150 °C Tj Maximum junction temperature 150 °C Rthja Thermal resistance junction to ambient(5) SO-8 TSSOP8 DIP8 MiniSO-8 5. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 125 120 85 190 °C/W Rthjc Thermal resistance junction to case(5) SO-8 TSSOP8 DIP8 MiniSO-8 40 37 41 39 °C/W ESD HBM: human body model(6) 6. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k 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 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. 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 |
