Maxim Integrated
MAX5713/MAX5714/MAX5715
Ultra-Small, Quad-Channel, 8-/10-/12-Bit Buffered
Output DACs with Internal Reference and SPI Interface
CONFIG Command
The CONFIG command (B[23:20] = 0110) updates the
LDAC and LOAD functions of selected DACs. Issue the
command with B16 = 0 to allow the DAC latches to oper-
ate normally or with B16 = 1 to disable the DAC latches,
making them perpetually transparent. Mode settings of
the selected DACs are updated while the mode settings
of the rest of the DACs remain unchanged; DAC(s) are
selected by bits B[11:8]. See Table 6.
REF Command
The REF command updates the global reference setting
used for all DAC channels. Set B[17:16] = 00 to use an
external reference for the DACs or set B[17:16] to 01, 10,
or 11 to select either the 2.5V, 2.048V, or 4.096V internal
reference, respectively.
If RF2 (B18) is set to zero (default) in the REF command,
the reference will be powered down any time all DAC
channels are powered down (in STANDBY mode). If RF2
(B18 = 1) is set to one, the reference will remain powered
even if all DAC channels are powered down, allowing
continued operation of external circuitry. In this mode,
the 1FA shutdown state is not available. See Table 7.
