PRELIMINARY TECHNICAL DATA
DAC1 Setup
The resolution of DAC1 is 4.7mV this is scaled up by 6 to
give COM_OUT amplitude resolution of 28mV (4.7mV *
6 = 28mV). The COM_OUT amplitude Vp-p is given by,
(Binary Code/255)(1.188)(6)= Vp-p (COM_OUT).
A table of the min, max and typical values for COM_OUT
amplitude is given in the Table 1 below.

DAC2 Setup
The resolution of DAC2 is 4.7mV this is scaled up by 3 to
give you the COM_OUT centre voltage resolution of
14mV (4.7mV * 3 = 14mV). The COM_OUT centre
voltage is given by,
(Binary Code/255)(1.188)(3)= COM_OUT DC Voltage.
A table of the min, max and typical values for COM_OUT
centre voltage is given in the Table 2 below.
