MAX9890

Audio Click-Pop Suppressor

General Description

Features

● 36dB Click-Pop Suppression

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 ramp-

ing of the DC bias voltage on the output-coupling capaci-

tors 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.

● 2.7V to 5.5V Single-Supply Operation

● Clickless/Popless Startup/Power-Up and

Shutdown/Power-Down

● 0.001μA Low-Power Shutdown Mode

● THD+N < 0.003% Into 32Ω

● ±8kV ESD Protected Outputs (Human Body Model)

● Requires Only One 0.1μF Capacitor to Complete the

Circuit

● Low 14μA Supply Current

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) pro-

tection circuitry on the outputs protect the MAX9890 and

devices further up the signal chain from ESD strikes up

to ±8kV.

● Tiny Packaging

• 9-Bump UCSP (1.5mm x 1.5mm x 0.6mm)

• 8-Pin TDFN (3mm x 3mm x 0.8mm)

Ordering Information

The MAX9890 is available in a miniature (1.5mm x 1.5mm

x 0.6mm) 9-bump chip-scale package (UCSP™), as well

as an 8-pin TDFN package (3mm x 3mm x 0.8mm), and is

specified for operation over the -40°C to +85°C extended

temperature range.
