Absolute maximum ratings
Stresses above those listed as 'absolute maximum ratings' may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect the device reliability.

1. All power V_DDX (V_DD, V_DDA) and ground V_SSX (V_SS, V_SSA) pins must always be connected to the external
power supply.
2. I_INJ(PIN) must never be exceeded. This is implicitly insured if V_IN maximum is respected. If V_IN maximum
cannot be respected, the injection current must be limited externally to the I_INJ(PIN) value. A positive
injection is induced by V_IN > V_DD while a negative injection is induced by V_IN < V_SS.
3. V_SS and V_SSA signals must be interconnected together with a short wire loop.

2. All power V_DDX (V_DD, V_DDA) and ground V_SSX (V_SS, V_SSA) pins must always be connected to the external
power supply.
3. I_INJ(PIN) must never be exceeded. This is implicitly insured if V_IN maximum is respected. If V_IN maximum
cannot be respected, the injection current must be limited externally to the I_INJ(PIN) value. A positive
injection is induced by V_IN > V_DD while a negative injection is induced by V_IN < V_SS.
4. Negative injection disturbs the analog performance of the device.
