Typical Operating Circuit/Functional Diagram
Typical Operating Characteristics (continued)
(VDD = PVDD = SHDN = MUTE = 5V, GND = PGND = 0V, SYNC = VDD (SSM), unless otherwise noted. Gain = 12dB (G1 = 0, G2 = 1).
THD+N measurement bandwidth: 22Hz to 22kHz. Typical values are at TA = +25°C.) (See Typical Operating Circuit)
