Writing to the DACA_OP output register updates DACA
on the rising SCLK edge of the LSB data bit. The output
voltage can be calculated as follows:
where V
is the integer value of the DACA<9:0> output register.
The output buffer is in unity gain. The DACA data is 10
bits long and right justified.
Writing to the DACB_OP output register updates DACB
on the rising SCLK edge of the LSB. The output voltage
can be calculated as follows:
where V
is the integer value of DACB<9:0> output register. The
output buffer is in unity gain. The DACB data is 10 bits
long and right justified.

DAE: DACA enable bit. Set DAE = 1 to power up the
DACA and the DACA output buffer in the MAX1358B.
DBE: DACB enable bit. Set DBE = 1 to power up the
DACB and the DACB output buffer in the MAX1358B.
This bit is mirrored in the DACB_OP register.
OP1E: OP1 power-enable bit. Set OP1E = 1 to power
up OP1 in the MAX1358B. This bit is mirrored in the
DACB_OP register.
DACA<9:0>: DACA data bits.
DAE: DACA enable bit. Set DAE = 1 to power up
DACA and the DACA output buffer in the MAX1358B.
This bit is mirrored in the DACA_OP register.
DBE: DACB enable bit. Set DBE = 1 to power up DACB
and the DACB output buffer in the MAX1358B. This bit is
mirrored in the DACA_OP register.
OP1E: OP1 power-enable bit. Set OP1E = 1 to power
up OP1 in the MAX1358B. This bit is mirrored in the
DACA_OP register.
