30 / 56 page  WM8510 Product Preview w PP Rev 1.2 December 2004 30 ANALOGUE OUTPUTS 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 15. Figure 15 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. When this boost is enabled the output DC level is also level shifted (from AVDD/2 to 1.5xAVDD/2) to prevent the signal from clipping. A dedicated amplifier, as shown in Figure 15, 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 13 summarises the effect of the SPKBOOST/MONOBOOST control bits. |
