ELECTRICAL CHARACTERISTICS All the parameters are given in the capless configuration (typical application).
The following parameters are given for the NCP2809A and NCP2809B mounted externally with 0 dB gain, unless otherwise noted.
(For typical values TA = 25°C, for min and max values TA = 40°C to 85°C, TJmax = 125°C, unless otherwise noted.)

7. Min/Max limits are guaranteed by production test.
8. This thermal shutdown is made with an hysteresis function. Typically, the device turns off at 160°C and turns on again when the junction
temperature is less than 140°C.
9. The outputs of the device are sensitive to a coupling capacitor to Ground. To ensure THD+N at very low level for any sort of headset
(16 W or 32 W), outputs (OUT_R, OUT_L, OUT_I and REF_I) must not be grounded with more than 500 pF.
