DirectDrive Headphone Amplifiers

ELECTRICAL CHARACTERISTICS (continued)

(VDD = PVDD = CPVDD = HPVDD = 5V, GND = PGND = CPGND = 0V, SHDN = VDD, CBIAS = 1µF, C1 = C2 = 1µF, speaker load

terminated between OUT_+ and OUT_-, headphone load terminated between HPOUT_ and GND, GAIN1 = GAIN2 = VOL = GAIN = 0V,

TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.

Note 2: Guaranteed by design. Not production tested.

Note 3: PSRR is specified with the amplifier input connected to GND through CIN.

Note 4: Output power levels are measured with the thin QFN’s exposed paddle soldered to the ground plane.

Note 5: See Table 3 for details of the mute levels.

Note 6: The value of RB dictates the minimum beep signal amplitude (see the Beep Input section).
