... The Click and Pop elimination is effective into low and high impedance loads and requires no external timing components to deal with DC blocking capacitors placed between the single supply codec and the load. The ISL54406 is available TDFN (3mmx3mm tiny 10 Ld TQFN (1.8mmx1.4mm) ultra-thin package. It µ ...

... The discussion that follows will describe using the ISL54406 in the “Application Block Diagram” on page 7. LOGIC CONTROL The state of the ISL54406 device is determined by the logic level at the SEL1 and SEL2 pins. The part has four states or modes of operation. The Audio Playback Mode, Audio Mute Mode, Click and Pop Mode, and Shutdown Mode. Refer to “ ...

... In a high impedance state, 4MΩ internal pull down resistors on the SEL1 and SEL2 pins will set the ISL54406 logic pins to “0”. This will put the switch in the SHDN state which turns all switches OFF and deactivates the Click and Pop circuitry which will minimize power supply currents and increase battery life ...
