Typical Operating Characteristics—Headphone Mode (continued)
(VDD = PVDD = HPVDD = 5V, GND = PGND = CPGND = 0V, SHDN = VDD, GAIN1 = GAIN2 = GND (+9dB), FS0 = FS1 = GND (800Hz),
MGAIN = float (-6dB), SYNC_IN = VDD (SSM), speaker load RL connected between OUT+ and OUT-, unless otherwise noted, RL =
∞.
Headphone load RLH connected between HPR/HPL to GND. CBIAS = 1F to GND, 1F capacitor between C1P and C1N, CVSS = 1F.
TA = TMIN to TMAX, unless otherwise noted. Typical values at TA = +25°C.)
