DAC1005D750
Dual 10-bit DAC, up to 750 Msps; 4x and 8x interpolating
The auxiliary DACs can be used to control the offset in a precise range or with precise
steps.
Figure 17
provides an example of a DC interface with the auxiliary DACs to an AQM with
a 1.7 V
I(cm)
common-mode input level.
Figure 18
provides an example of a DC interface with the auxiliary DACs to an AQM with
a 3.3 V
I(cm)
common-mode input level.
