DAC Control Register
The DAC Control register configures the power states for
DACA, DACB, the op amps, DAC reference buffer, and
the internal reference. The DAC Control register also
controls the DACA and DACB input and output register
write modes. At power-up, all DACs and op amps are
powered down. When powered down, the outputs of the
DAC buffers and op amps are high impedance.
DAPD<1:0>: DACA Power-Down bits (default = 00).
DAPD<1:0> control the power-down states and write
modes for DACA (see Table 14).
DBPD<1:0>: (MAX1329 only) DACB Power-Down bits
(default = 00). DBPD<1:0> control the power-down states
and write modes for a DACB write as shown in Table 15.
OA1E: Op Amp 1 Enable bit (default = 0). Set OA1E = 1
to power up op amp 1.
OA2E (MAX1330 only): Op Amp 2 Enable bit (default =
0). Set OA2E = 1 to power up op amp 2.
DREF<1:0>: DAC Reference Buffer bits (default = 00).
DREF<1:0> sets the DAC reference buffer gain when
REFE = 0 (see Table 16). DREF<1:0> sets the REFDAC
voltage when the REFE = 1.
REFE: Internal Reference Enable bit (default = 0). REFE
= 1 enables the internal reference and sets REFADJ to
2.5V. REFE = 0 disables the internal reference so an
external reference can be applied at REFADJ, which
drives the inputs to the ADC and DAC reference
buffers. This bit is mirrored in the ADC Control register
so that writing either location updates both bits.
