ANALOGUE OUTPUTS
w
The WM8510 has a single MONO output and two outputs SPKOUTP and SPOUTN for driving a
mono BTL speaker. These analogue output stages are supplied from SPKVDD and are capable of
driving up to 1.5V rms signals (equivalent to 3V rms into a bridge tied speaker) as shown in Figure
20.
Figure 20 Speaker and Mono Analogue Outputs
The Mono and speaker outputs have output driving stages which can be controlled by the register
bits MONOBOOST and SPKBOOST respectively. Each output stage has a selectable gain boost of
1.5x.
1.5xAVDD/2) to prevent the signal from clipping. A dedicated amplifier, as shown in Figure 20, is
used to perform the DC level shift operation. This buffer must be enabled using the BUFDCOPEN
register bit for this operating mode. It should also be noted that if SPKVDD is not equal to or greater
than 1.5xAVDD this boost mode may result in signals clipping. Table 30 summarises the effect of
the SPKBOOST/MONOBOOST control bits.
When this boost is enabled the output DC level is also level shifted (from AVDD/2 to
