_______________Detailed Desc ription
The MAX5130/MAX5131 13-bit, voltage-output DACs
are easily configured with a 3-wire serial interface. They
include a 16-bit data-in/data-out shift register and have
a double-buffered input consisting of an input register
and a DAC register. In addition, these devices employ
precision bandgap references and trimmed internal
resistors to produce a gain of 1.6384V/V, maximizing
the output voltage swing (Figure 1). The MAX5130/
MAX5131 output amplifier’s offset-adjust pin allows for
a DC shift in the DAC outputs. The full-scale output volt-
age is +4.0955V for the MAX5130 and +2.04775V for
the MAX5131. These DACs are designed with an invert-
ed R-2R ladder network (Figure 2) that produces a
weighted output voltage proportional to the digital input
code.
Internal Referenc e
Both the MAX5130 and MAX5131 use an on-board pre-
cision bandgap reference to generate an output volt-
age of +2.5V (MAX5130) or +1.25V (MAX5131). With a
low temperature coefficient of only 10ppm/°C (max),
the REF pin can source up to 100μA and may become
unstable with capacitive loads exceeding 100pF.
REFADJ can be used for minor adjustments (1%) to the
