High output current allows low load impedances The device is stable for capacitive loads up to to be driven. An internal low impedance phantom 500 pF. When the STANDBY mode is enabled, the ground eliminates the need for an external total consumption drops to 6 A (V = 3 V). CC reference voltage or biasing arrangement.

All voltage values, except differential voltage are with respect to network ground terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > 1 V, the maximum input current must not exceed 1mA. In this case (Vid > 1V), an input series resistor must be added to limit input current. 3. Human body model: 100pF discharged through a 1.5 k resistor into pin of device. 4. 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 ), into pin-to-pin of device. 5. There is no short-circuit protection inside the device: short-circuits from the output to V can cause cc excessive heating. The maximum output current is approximately 80 mA, independent of the magnitude of V . Destructive dissipation can result from simultaneous short-circuits on all amplifiers. cc Table 2.
