Overview
...pression for devices such as CODECs with test integrated headphone amplifiers that lack a clickless/popless startup/power-up or shutdown/power-down.
The device controls the ramping of the DC bias voltage on the output-coupling capacitors and the application of the audio signal to ensure that no audible transients are present at the headphones.
The MAX9890A features a 200ms startup time for use with up to 100μF coupling capacitors.
The MAX9890B features a 330ms startup time for use with greater than 100μF coupling capacitors.
The MAX9890 consumes 14μA of supply current and 0.
001μA in shutdown, while contributing less than 0.
003% THD+N into a 32Ω load.
