600 µA supply current — the power budget decision
Total supply current is 600 µA for all four amplifiers, or 150 µA per channel. That keeps the quiescent draw low enough for always-on sensor interfaces in battery-backed modules, without sacrificing the 35 mA output drive per channel. The input bias current of 2.5 pA (typical) and input offset voltage of 250 µV (max) suit precision DC-coupled stages like thermocouple or pressure-sensor amplifiers.
Temperature range and operating environment
No derating needed for under-hood or cabin deployment.
