SPECIFICATION RANGES
For the AD7225 to operate to rated specifications, its input
reference voltage must be at least 4 V below the VDD power
supply voltage. This voltage differential is the overhead voltage
required by the output amplifiers.
The AD7225 is specified to operate over a VDD range from 12 V
± 5% to 15 V ± 10% (that is, from 11.4 V to 16.5 V) with a VSS
of 5 V ± 10%. Operation is also specified for a single 15 V ±
5% VDD supply. Applying a VSS of 5 V results in improved zero-
code error, improved output sink capability with outputs near
AGND, and improved negative-going settling time.
Performance is specified over a wide range of reference voltages
from 2 V to (VDD 4 V) with dual supplies. This allows a range
of standard reference generators to be used, such as the AD780,
a 2.5 V band gap reference, and the AD584, a precision 10 V
reference. Note that an output voltage range of 0 V to 10 V
requires a nominal 15 V ± 5% power supply voltage.
