Note 7: Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then discharged directly into the
IC with no external series resistor (resistance of discharge path must be under 50Ω).
Note 8: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 9: The given θ
Note 10: Please refer to the Output Noise vs Output Mode table in the Typical Performance Characteristics section for more details.

This is the input coupling capacitor. It blocks the DC voltage at, and couples the the input signal to, the
amplifier’s input terminals. C
This is the supply bypass capacitor. It provides power supply filtering.
This is the BYPASS pin capacitor. It provides half-supply filtering.
