Stereo Class D Audio Subsystem

with DirectDrive Headphone Amplifier

ELECTRICAL CHARACTERISTICS (continued)

(VDD = VPVDDL = VPVDDR = 3.7V, VCCIO = 1.8V, VGND = VPGNDL = VPGNDR = 0. Single-ended inputs, preamp = 0dB, volume controls =

0dB, BYPASS = 0, SHDN = 1. Speaker loads connected between OUT_+ and OUT_-. Headphone loads connected from HPL or HPR to

GND. RSPK = ∞, RHP = ∞. C1 = C2 = CBIAS = 1µF. TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

Note 3: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.

Note 4: Class D amplifier testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For

RSPKR = 8Ω, L = 68mH.

Note 5: Amplifier inputs are AC-coupled to GND.

Note 6: CB is in pF.
