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 voltages values are measured with respect to the ground pin.
3. The magnitude of input signal must never exceed V_CC + 0.3V / GND - 0.3V.
4. 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, involves abnormal operating condition.
6. The magnitude of 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 shall be obtained when V_STBY = GND.
5. With heat sink surface = 125mm².
