Low RF Susceptibility, Mono Audio
Subsystem with DirectDrive Headphone Amplifier
Typical Operating Characteristics (continued)
(VDD = PVDD = 3.7V, VGND = VPGND = 0V. Single-ended inputs, preamp gain = 0dB, volume controls = 0dB, OSC = 00, BYPASS =
0, SHDN = 1. Speaker loads (ZSPK) connected between OUT+ and OUT-. Headphone loads (RHP) connected from HPL or HPR to
GND. ZSPK = ∞, RHP = ∞. C1 = C2 = CBIAS = 1µF. TA = +25°C, unless otherwise noted.)
