Settling-Time-Mode Bits (SPDA, SPDB)
The settling-time-mode bits select the settling time
(FAST mode or SLOW mode) of the MAX5290
–
MAX5295. Set SPD_ = 1 to select FAST mode or set
SPD_ = 0 to select SLOW mode, where
“
_
”
is replaced
by A or B, depending on the selected channel (see
Table 12). FAST mode provides a 3μs maximum set-
tling time and SLOW mode provides a 10μs maximum
settling time. Default settling-time mode bits are [0, 0]
(SLOW mode for both DACs).
Settling-Time-Mode Write Example:
To configure DACA into FAST mode and DACB into
SLOW mode, use the command in Table 13.
To read back the settling-time-mode bits, use the com-
mand in Table 14.
CPOL and CPHA Control Bits
The CPOL and CPHA control bits of the
MAX5290
–
MAX5295 are defined the same as the CPOL
and CPHA bits in the SPI standard. Set the CPOL = 0
and CPHA = 0 or set CPOL = 1 and CPHA = 1 for
MICROWIRE and SPI applications requiring the clocking
of data in on the rising edge of SCLK. Set the CPOL = 0
