PIN DESCRIPTIONS (continued)
DESCRIPTION
Analog ground
Positive analog power for DAC6-OUT, DAC7-OUT, DAC8-OUT, DAC9-OUT, DAC10-OUT, DAC11-OUT, must
be tied to AV_CC2
Internal reference output
DAC reference Input
Output of DAC channels 9, 10, and 11
Global alarm. Open drain output. External 10kΩ pull-up resistor required. This pin goes low (active) when one
(or more) of the analog channels are out of range.
DAC clear control signal, digital input, active low. When low, all DACs associated with the DAC-CLR-1 pin enter
a clear state, the DAC Latch is loaded with predefined code, and the output is set to the corresponding level.
However, the DAC-Data Register does not change. When the DAC goes back to normal operation, the DAC
Latch is loaded with the previous data from the DAC-Data Register and the output returns to the previous level,
regardless of the status of the SLDAC-n bit. When this pin is high, the DACs are in normal operation.
