Audio Click-Pop Suppressor

General Description

Features

The MAX9890 provides click-and-pop suppression for

devices such as CODECs with 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 Circuit

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 (Human Body

Model) protection circuitry on the outputs protect the

MAX9890 and devices further up the signal chain from

ESD strikes up to 8kꢀ.

1.5mm ✕ 0.6mm) 9-bump chip-scale package (UCSP™),

as well as an 8-pin TDFN package (3mm ✕ 3mm ✕

0.8mm), and is specified for operation over the

-40°C to +85°C extended temperature range.
