MAX5893
For stable operation with the internal reference, REFIO
should be decoupled to GND with a 1F capacitor.
REFIO must be buffered with an external amplifier, if
heavy loading is required, due to its 10k
output resis-
tance.
Alternatively, apply a temperature-stable external refer-
ence to REFIO (Figure 18). The internal reference is over-
driven by the external reference. For improved accuracy
and drift performance, choose a fixed output voltage ref-
erence such as the MAX6520 bandgap reference.
The MAX5893’s reference circuit (Figure 19) employs a
control amplifier, designed to regulate the full-scale
current IOUT for the differential current outputs of the
DAC. The output current can be calculated as:
IOUTFS = 32 x IREFIO - 1LSB
IOUTFS = 32 x IREFIO - (IOUT/212)
where IREFIO is the reference output current (IREFIO =
VREFIO/RSET) and IOUT is the full-scale output current
of the DAC. Located between FSADJ and DACREF,
RSET is the reference resistor, which determines the
amplifier’s output current for the DAC. Use Table 5 for a
matrix of different IOUTFS and RSET selections.
