Power up individual DAC buffers indicated by data
in DAC0 through DAC3. A one indicates the DAC
output is connected and active. A zero does not
affect the DAC’s present state.
Power down individual DAC buffers indicated by
data in DAC0 through DAC3. A one indicates the
DAC output is disconnected and high impedance.
A zero does not affect the DAC’s present state.
Power down individual DAC buffers indicated by
data in DAC0 through DAC3. A one indicates the
DAC output is disconnected and pulled to AGND
with a 1kΩ resistor. A zero does not affect the DAC’s
present state.
Power down individual DAC buffers indicated by
data in DAC0 through DAC3. A one indicates the
DAC output is disconnected and pulled to AGND
with a 100kΩ resistor. A zero does not affect the
DAC’s present state.
Power down individual DAC buffers indicated by
data in DAC0 through DAC3. A one indicates the
DAC output is disconnected and pulled to REF1 with
a 100kΩ resistor. A zero does not affect the DAC’s
present state.
DESCRIPTION
DAC0–7
DAC0–7
D11–D0 to input registers 0–7
(MAX1221/MAX1223). D11–D0 to
input registers 0–3 (MAX1343).
DAC outputs unchanged.
Input registers to DAC registers
indicated by ones, DAC outputs
updated, equivalent to software
LDAC. (No effect on DACs
indicated by zeros.) DAC7–DAC4
are only valid on the MAX1221/
MAX1223. These are don’t-care
bits for the MAX1343.
