Typical Operating Characteristics (continued)

(VDD = SHDN = 5V, PGND = SGND = 0V, C1 = C2 = 1µF, CPREG = CNREG = 1µF, BM_ = 0V, RIN = 10kΩ, RF = 10kΩ, maximum vol-

ume (overall gain = 0dB), BassMax disabled. Load connected between OUT_ and PGND where specified. Outputs in phase, both

channels loaded. TA = +25°C, unless otherwise noted.) (See the Functional Diagram/Typical Operating Circuit)
