Subsystem with DirectDrive Headphone Amplifier

ELECTRICAL CHARACTERISTICS (continued)

(VDD = VPVDD = 3.7V, VGND = VPGND = 0V. Single-ended inputs, preamp gain = 0dB, volume controls = 0dB, OSC = 00, SHDN = 1.

Speaker loads (ZSPK) connected between OUT+ and OUT-. Headphone loads (RHP) connected from HPL or HPR to GND. SDA and

SCL pullup voltage = 3.3V. ZSPK = ∞, RHP = ∞. C1 = C2 = CBIAS = 1µF. TA = TMIN to TMAX, unless otherwise noted. Typical values are

at TA = +25°C.) (Note 3)

Note 3: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.

Note 4: Amplifier inputs are AC-coupled to GND.

Note 5: Output levels higher than 825mW are not recommended for extended durations. Production tested with ZSPK = 8Ω + 68µH only.
