Many configuration options in the ICs can be made
while the devices are operating, however, some regis-
ters should only be adjusted when the corresponding
audio path is disabled. Table 39 lists the registers that
are sensitive during operation. Either disable the cor-
responding audio path or set SHDN = 0 while changing
these registers.
In applications where speaker leads exceed 20mm,
additional EMI suppression can be achieved by using a
filter constructed from a ferrite bead and a capacitor to
ground (Figure 42). Use a ferrite bead with low DC resis-
tance, high-frequency (> 600MHz) impedance between
100I and 600I, and rated for at least 1A. The capacitor
value varies based on the ferrite bead chosen and the
actual speaker lead length. Select a capacitor less than
1nF based on EMI performance.
An input capacitor, C
impedance of the IC line inputs forms a highpass filter

that removes the DC bias from an incoming analog
signal. The AC coupling capacitor allows the amplifier
to automatically bias the signal to an optimum DC level.
Assuming zero-source impedance, the -3dB point of the
highpass filter is given by:
Choose C
quency of interest. For best audio quality use capacitors
whose dielectrics have low-voltage coefficients, such as
tantalum or aluminum electrolytic. Capacitors with high-
voltage coefficients, such as ceramics, may result in
increased distortion at low frequencies.
Use capacitors with an ESR less than 100mI for optimum
performance. Low-ESR ceramic capacitors minimize the
output resistance of the charge pump. Most surface-
mount ceramic capacitors satisfy the ESR requirement.
For best performance over the extended temperature
range, select capacitors with an X7R dielectric.
