Offsetting DAC Outputs
Figure 7.shows examples of offset circuits.
DAC offset effects
When using the device in single supply applications, and
minimum reference voltage, there is a possibility that the DAC
output will not change when the code is incremented from 0.
Once the DAC has reached the offset voltage of the output
buffer, the DAC output will begin to increment in a normal opera-
tion.
5V Operation
The MP7226 can be operated with a single power supply
(V
DD
= +5V ) or dual power supplies ( V
DD
= +5V and V
SS
=
–5V) . The reference voltage range is reduced along with Some
performance parameter degradation. However the DNL of each
DAC remains at
1 LSB guaranteeing monotonicity.
