NAME
FUNCTION
1
M/Z
Reset Select Input. M/Z selects the default state of the analog output (OUT) after power-on or hardware or
software reset. Connect M/Z to VDDIO to set the default output voltage to midscale or to DGND to set the
default output voltage to zero scale.
2
BUSY
Digital Input/Open-Drain Output. Connect a 5.1kI pullup resistor from BUSY to VDDIO. BUSY goes low
immediately after writing to the DIN register. During this time, the user can continue writing new data to
the DIN register, but no further updates to the DAC register and DAC output can take place. If LDAC
is asserted low while BUSY is low, this event is stored. BUSY is bidirectional, and can be asserted low
externally to delay LDAC action. BUSY also goes low during power-on reset, when RST is low, or when
software reset is activated.
3
LDAC
Active-Low Load DAC Logic Input. If LDAC is taken low while BUSY is inactive (high), the contents of the
input registers are transferred to the DAC register and the DAC output is updated. If LDAC is taken low
while BUSY is asserted low, the LDAC event is stored and the DAC register update is delayed until BUSY
deasserts. Any event on LDAC during power-on reset or when RST is low is ignored.
4
DOUT
SPI Bus Serial Data Output. See the Serial Interface section for details.
