MAX9890
External Capacitor (CCEXT)
The external click-pop suppression capacitor at CEXT
serves a dual purpose. On power-up, CCEXT is
charged by an internal current source and is used to
slowly ramp up the external coupling capacitors. When
the device is powered down, CCEXT powers the internal
circuitry used to drain the external coupling capacitors.
A 0.1F capacitor between CEXT and GND provides
clickless/popless operation with coupling capacitors for
both the MAX9890A and MAX9890B, even with the
rapid removal of supply voltage.
Applications Information
Layout
Good layout improves performance by decreasing the
amount of stray capacitance and noise. To decrease
stray capacitance, minimize PC board trace lengths
and resistor leads, and place external components as
close to the device as possible.
Power Supply and Bypassing
The excellent PSRR of the MAX9890 allows it to operate
from noisy power supplies. In most applications, a
0.1F capacitor from VCC to GND is sufficient. This
bypass capacitor should be placed close to VCC.
