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:
V_OUTA = V_REF x N/2¹⁰
where V_REF is the reference voltage for the DAC, and N
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.
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.
