1. Caution: This device is not protected in the event of abnormal operating conditions, such as for example,
short-circuiting between any one output pin and ground, between any one output pin and V_CC, and
between individual output pins.
2. All voltage values are measured with respect to the ground pin.
3. The magnitude of the input signal must never exceed V_CC + 0.3V / GND - 0.3V.
4. The device is protected in case of over temperature by a thermal shutdown active @ 150°C.
5. Exceeding the power derating curves during a long period causes abnormal operation.
6. The magnitude of the standby signal must never exceed V_CC + 0.3V / GND - 0.3V.

1. For V_CC from 2.4V to 2.5V, the operating temperature range is reduced to 0°C ≤T_amb ≤70°C.
2. For V_CC from 2.4V to 2.5V, the common mode input range must be set at V_CC/2.
3. Without any signal on V_STBY, the device will be in standby.
4. Minimum current consumption is obtained when V_STBY = GND.
5. With heat sink surface = 125mm².
