TPA5050
SLOS492B – MAY 2006 – REVISED MAY 2007
The TPA5050 draws different amounts of supply current depending upon the conditions under which it is
operated. As V
DD
increases, so too does I
DD
. Likewise, as V
DD
decreases, I
DD
decreases. The same is true of
the sampling frequency, fs. An increase in fs causes an increase in I
DD
. Figure 11 illustrates the relationship
between operating condition and typical supply current.
