An active low pulse, at any time, on the RESET pin asynchro-
nously forces all DAC register bits to zero. T he DAC output
voltage becomes zero volts and stays at that value until a new
data word is loaded into the DAC register with a new
WR
com-
mand. T he equivalent input logic for the DAC register loading
is shown in Figure 9.
