_______________Detailed Description

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 Reference

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
