reset; active LOW, depending on the state of
RSTSEL, the DAC register is either reset to mid-
scale or min-scale.
DAC register load control, rising edge triggered.
Data is loaded from the input register to the DAC
register.
Chip Select, active LOW
Enabled by CS, controls data read (HIGH) and
write (LOW) from or to the input register.
Reset Select; determines the action of RST. If
HIGH, RST will reset the DAC register to mid-
scale. If LOW, RST will reset the DAC register to
min-scale.
Enables internal +10V reference (REF
OUT
), active
LOW.
Internal Reference Output
Internal Reference Trim. (Acts as a gain
adjustment input when the internal reference is
used.)
