General Description
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 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
Ω 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.
The MAX9890 is available in a miniature (1.5mm
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.
