The MAX9890 provides click-and-pop suppression for devices such as CODECs with integrated headphone amplifiers that lack a clickless/popless startup/powerup 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 100F coupling capacitors. The MAX9890B features a 330ms startup time for use with greater than 100F coupling capacitors. The MAX9890 consumes 14A of supply current and 0.001A in shutdown, while contributing less than 0.003% THD+N into a 32 load. ESD (Human Body Model) protection circuitry on the outputs protect the MAX9890 and devices further up the signal chain from ESD strikes up to 8kV. |
