1. All voltage values are measured with respect to the ground pin.

2. The magnitude of the input signal must never exceed VCC + 0.3V / GND - 0.3V.

3. The device is protected in case of over temperature by a thermal shutdown active @ 150°C.

4. Exceeding the power derating curves during a long period will cause abnormal operation.

1. I Voo I ≤ 35mV max with both differential gains.

2. Without any signal on VSTBY, the device is in standby (internal 300kΩ pull down resistor).

3. Minimum current consumption is obtained when VSTBY = GND.

4. When mounted on 4-layer PCB.
