MAX9890 Audio Click-Pop Suppressor

The MAX9890 provides click-and-pop suppression 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 t.

MAX9890 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. ESD (Huma
