Digital Control of Gain and Offset
The two DACs can be used to control the offset and
gain for curve-fitting nonlinear functions, such as trans-
ducer linearization or analog compression/expansion
applications. The input signal is used as the reference
for the gain-adjust DAC, whose output is summed with
the output from the offset-adjust DAC. The relative
weight of each DAC output is adjusted by R1, R2, R3,
and R4 (Figure 11).
Sharing a Common DIN Line
Several MAX5234/MAX5235 may share one common
DIN signal line (Figure 12). In this configuration, the
data bus is common to all devices; data is not shifted
through a daisy-chain. The SCLK and DIN lines are
shared by all devices, but each IC needs its own dedi-
cated
CS
line.
Power-Supply Considerations
On power-up, the input and DAC registers clear (set to
zero code). Bypass the power supply with a 4.7μF
