Note 1: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2: Measured at headphone outputs.
Note 3: Amplifier inputs AC-coupled to GND.
Note 4: Testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For R
Note 5: MAX9775 only.
Note 6: Testing performed at room temperature with an 8Ω resistive load in series with a 68µH inductive load connected across BTL
Note 7: Guaranteed by design.
