on-reset. Using this feature, the
SP9504
can be
configured such that during power-up, the
second register will be digitally “zeroed”,
producing a zero volt output at each of the four
DAC outputs. This is achieved by powering the
unit up with XFER in a high state. Thus, with no
external circuitry, the
SP9504
can be powered
up with the analog outputs at a known, zero volt
output level.
TEMPORARILY FORCING
ALL DAC OUTPUTS TO 0V
Set
WR1=1, CS=1, WR2=0, XFER=0. The DAC
registers can be temporarily forced to 1000 0000
0000 by bringing the CLR pin low. This will
force the DAC outputs to 0V, while the CLR pin
remains low. When the CLR pin is brought back
high, the digital code at the DAC registers will
again appear at the DAC's digital inputs, and the
analog outputs will return to their previous values.
