Key specifications include operation from 1.6 to 4.0V with a recommended 3.0V supply, driving a 16 to 32Ω load, and strong ripple rejection. The device integrates a power switch with built-in muting and provides low quiescent current, low noise voltage (7 μV), and controlled output characteristics such as gain, THD, crosstalk, and sensitivity across defined test
