AD7294
Data Sheet
Rev. H | Page 26 of 48
The AD7294 can also operate with an external reference.
Suitable reference sources for the AD7294 include AD780,
AD1582, ADR431, REF193, and ADR391. In addition, choosing
a reference with an output trim adjustment, such as the ADR441,
allows a system designer to trim system errors by setting a
reference voltage to a voltage other than the nominal.
Long-term drift is a measure of how much the reference drifts
over time. A reference with a low long-term drift specification
ensures that the overall solution remains stable during its entire
lifetime. If an external reference is used, select a low temperature
coefficient specification to reduce the temperature dependence
of the system output voltage on ambient conditions.
VDRIVE FEATURE
The AD7294 also has a VDRIVE feature to control the voltage at
which the I2C interface operates. The VDRIVE pin is connected to
the supply to which the I2C bus is pulled. This pin sets the input
and output threshold levels for the digital logic pins and the
ISENSE OVERRANGE pins. The VDRIVE feature allows the AD7294
to easily interface to both 3 V and 5 V processors. For example,
if the AD7294 is operated with a VDD of 5 V, the VDRIVE pin can
be powered from a 3 V supply, allowing a large dynamic range
with low voltage digital processors. Thus, the AD7294 can be
used with the 2 × VREF input range with a VDD of 5 V, yet remains
capable of interfacing to 3 V digital parts. Decouple this pin to
DGND with a 100 nF and a 1 μF capacitor.
