4 / 21 page ![]() Absolute maximum ratings and operating conditions TS922 4/21 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. 14 V Vid Differential input voltage (2) 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > ±1V, the maximum input current must not exceed ±1mA. In this case (Vid > ±1V) an input series resistor must be added to limit input current. ±1 V Vin Input voltage (3) 3. Do not exceed 14V. VDD-0.3 to VCC+0.3 V Tstg Storage temperature -65 to +150 °C Rthja Thermal resistance junction to ambient (4) SO8 TSSOP8 DIP8 Flip-chip 4. Rth are typical values. 125 120 85 90 °C/W Rthjc Thermal resistance junction to case SO8 TSSOP8 DIP8 40 37 41 °C/W Tj Maximum junction temperature 150 °C ESD HBM: human body model(5) MM: machine model(6) CDM: charged device model 5. Human body model, 100pF discharged through a 1.5k Ω resistor into pin of device. 6. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5 Ω), into pin of device. 2 100 1.5 kV V kV Output short circuit duration see note(7) 7. There is no short-circuit protection inside the device: short-circuits from the output to VCC can cause excessive heating. The maximum output current is approximately 80mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. Latch-up immunity 200 mA Soldering temperature (10sec), leaded version Soldering temperature (10sec), unleaded version 250 260 °C Table 2.
