D11, D10,
XXXXXXXXXX
MAX5530 enters shutdown; MAX5531 enters standby*. For the
MAX5531, D11 and D10 configure the internal reference voltage
(Table 3).
1101
D11, D10,
XXXXXXXXXX
MAX5530/MAX5531 enter normal operation; DAC output reflects
existing contents of DAC register. For the MAX5531, D11 and D10
configure the internal reference voltage (Table 3).
1110
D11, D10,
XXXXXXXXXX
MAX5530/MAX5531 enter shutdown; DAC output set to high
impedance. For the MAX5531, D11 and D10 configure the internal
reference voltage (Table 3).
1111
12-bit data
Load input register and DAC register from shift register; DAC output
updated; MAX5530 enters normal operation if in shutdown;
MAX5531 enters normal operation if in standby or shutdown.
Table 2. Serial-Interface Programming Commands
X = Don’t care.
*Standby mode can be entered from normal operation only. It is not possible to enter standby mode from shutdown.
