The 1.6 mA quiescent supply per amplifier (both channels) keeps the power budget lean for multi-channel boards. Input bias current is 10 pA, so high-impedance sensor inputs won't see significant loading.
The pad is also the ground connection, so the PCB layout should match the datasheet's recommended land pattern.
