Production Data

WM9715L

Note that at low DCVDD voltages, the output range of the AUXDAC becomes limited, so that its

maximum RMS output voltage is the lesser of:

(DCVDD-0.7) / √2 Vrms

or AVDD / 3.3 Vrms

Under these circumstances, the AUXDAC cannot convert high digital input values to the correct

analogue equivalent; its digital input range must therefore be limited accordingly. If necessary, this

limitation can be circumvented by setting gains for the AUXDAC signal in register 12h, or by using a

higher DCVDD voltage.
