SLOS497A – JUNE 2006 – REVISED JULY 2006
The TPA5051 draws different amounts of supply current depending upon the conditions under which it is
operated. As VDD increases, so too does IDD. Likewise, as VDD decreases, IDD decreases. The same is true of
the sampling frequency, fs. An increase in fs causes an increase in IDD. Figure 12 illustrates the relationship
between operating condition and typical supply current.
