The bias generator of the selected DAC(s), output amplifier,
resistor string, and other associated linear circuitry are shut
down when the power-down mode is activated. The internal
reference is powered down only when all channels are powered
down. However, the contents of the DAC register are unaffected
when in power-down. The time to exit power-down is typically
4 s for DACVDD = 5 V.
Any combination of DACs can be powered up by setting PD1
and PD0 to 0 (normal operation). The output powers up to the
value in the input register (LDAC low) or to the value in the
DAC register before powering down (LDAC high).
DAC Clear Code Register
The DAC blocks have a hardware CLR pin that is an asynchron-
ous clear input for all 16 DACs. The CLR input is falling edge
sensitive. Bringing the CLR line low clears the contents of the
input register and the DAC registers to the data contained in
the user-configurable CLR register and sets the analog outputs
accordingly. This function can be used in system calibration to
load zero scale, midscale, or full scale to all channels together.
These clear code values are user-programmable by setting Bit DB1
and Bit DB0 in the CLR control register (see Table 17). The
default setting clears the outputs to 0 V. Command 0101 is
reserved for loading the clear code register (see Table 11).
The DAC exits clear code mode on the 32nd falling edge of
the next write to the DAC. If CLR is activated during a write
sequence, the write is aborted.
The CLR pulse activation time—the falling edge of CLR to
when the output starts to change—is typically 280 ns. However,
if outside the DAC linear region, it typically takes 520 ns after
executing CLR for the output to start changing.
See Table 18 for contents of the input shift register during the
loading clear code register operation.
