The MAX9890BETA+T is an audio click-pop suppressor in 8 pin TDFN package. It provides click-and-pop suppression for devices such as CODECs with integrated headphone amplifiers that lack a clickless/popless start-up/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 MAX9890B features a 330ms start-up 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 32ohm load. ESD (Human Body Model) protection circuitry on the outputs protects the MAX9890 and devices further up the signal chain from ESD strikes up to ±8KV. Typical applications include high-end notebook audio, PDAs, portable DVD players, cell phones and portable MP3 players.
