    Applications Information
    Unipolar Output
    Figure 7 shows the unity gain of the MAX5290 in a
    unipolar output configuration. Table 24 lists the unipolar
    output codes.
    Bipolar Output
    The MAX5290 outputs can be configured for bipolar
    operation, as shown in Figure 8. The output voltage is
    given by the following equation:
    V
    OUT_ 
    = V
    REF
    x (CODE - 2048) / 2048
    where CODE represents the numeric value of the
    DAC
    ’
    s binary input code (0 to 4095 decimal). Table 25
    shows digital codes and the corresponding output volt-
    age for the Figure 8 circuit.
    Configurable Output Gain
    The MAX5291/MAX5293/MAX5295 have force-sense out-
    puts, which provide a connection directly to the inverting
    terminal of the output op amp, yielding the most flexibility.
    The advantage of the force-sense output is that specific
    gains can be set externally for a given application. The
    gain error for the MAX5291/MAX5293/MAX5295 is speci-
    fied in a unity-gain configuration (op-amp output and
    inverting terminals connected) and additional gain error
    results from external resistor tolerances. The force-sense
    DACs allow many useful circuits to be created with only a
    few simple external components.
    An example of a custom, fixed gain using the
    MAX5291
    ’
    s force-sense output is shown in Figure 9. In
    this example, the external reference is set to 1.25V, and
    the gain is set to +1.1V/V with external discrete resis-
    tors to provide an approximate 0 to 1.375V DAC output
    voltage range.
    V
    OUT_
    = [(0.5 x V
    REF
    x CODE) / 4096] x [1 + (R2 / R1)]
    where CODE represents the numeric value of the
    DAC
    ’
    s binary input code (0 to 4095 decimal).
    In this example, if R2 = 12k
     and R1 = 10k
    , set the
    gain = 1.1V/V:
    V
    OUT_
    = [(0.5 x 1.25V x CODE) / 4096] x 2.2
