TPA5052

SLOS500A – JUNE 2006 – REVISED AUGUST 2006

Only a single decoupling capacitor (0.1

µF–1 µF) is required across VDD and GND. The DELx terminals can be

directly connected to VDD or GND. Table 1 describes the delay settings selectable via the DELx terminals. A

schematic implementation of the TPA5052 is shown in Figure 3.

Figure 3. TPA5052 Schematic

To avoid pops and clicks in the audio stream when the delay is changed, the TPA5052 holds each channel in an

internal mute mode until all the set number of samples have passed. For example, if the delay is set to 511

samples, the TPA5052 holds each channel in mute until all 511 samples of audio data have passed.
