MULTIPLE-BYTE READ
A multiple-byte data read transfer is identical to a single-byte data read transfer except that multiple data bytes
are transmitted by the TPA5051 to the master device as shown in
Figure 9
. With the exception of the last data
byte, the master device responds with an acknowledge bit after receiving each data byte.

TPA5051 Operation
The following sections describe the registers configurable via I
2
C commands for the TPA5051.
Only a single decoupling capacitor (0.1
μ
F–1
μ
F) is required across VDD and GND. The ADDx terminals can be
directly connected to VDD or GND.
Table 1
describes the I
2
C addresses selectable via the ADDx terminals. A
schematic implementation of the TPA5051 is shown in
Figure 10
.
