2 / 12 page LM158,A-LM258,A-LM358,A 2/12 SCHEMATIC DIAGRAM (1/2 LM158) 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 V Vid Differential Input Voltage +32 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 40mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit 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 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 -0.3V. 50 mA Toper Opearting Free-air Temperature Range -55 to +125 -40 to +105 0 to +70 °C Tstg Storage Temperature Range -65 to +150 °C 6 µA 4 µA 100 µA Q2 Q3 Q4 Q1 Inverting input Non-inverting input Q8 Q9 Q10 Q11 Q12 50 µA Q13 Output Q7 Q6 Q5 R SC V CC C C GND |
