TPA5052

SLOS500A – JUNE 2006 – REVISED AUGUST 2006

It is sometimes desirable to increase the delay time beyond the limit which one device provides. In such cases,

the TPA5052 device can be placed in a series to increase the delay. See Figure 4 for an example.

Figure 4. Two Devices in Series

The TPA5052 draws different amounts of supply current depending upon the conditions under which it is

between operating condition and typical supply current.
