Pin No.
Mnemonic
Description
14
CLEAR
Active High, Edge Sensitive Input. When this pin is asserted, the output current is set to the programmed
clear code bit setting. Only channels enabled to be cleared are cleared. For more information, see the
Asynchronous Clear section. When CLEAR is active, the DAC output register cannot be written to.
15
ALERT
Active High Output. This pin is asserted when there is no SPI activity on the interface pins for a preset time.
For more information, see the Alert Output section.
16
FAULT
Active Low, Open-Drain Output. This pin is asserted low when any of the following conditions is detected:
open circuit, PEC error, or an overtemperature condition (see the Fault Output section).
17
DGND
Digital Ground.
18
RESET
Hardware Reset, Active Low Input.
19
AV
DD
Positive Analog Supply Pin. The voltage range is from 9 V to 33 V.

21
CHARTA
HART Input Connection for DAC Channel A. For more information, see the HART Connectivity section.
22
IGATEA
Optional Connection for External Pass Transistor. Leave this pin unconnected when using the dc-to-dc
converter. For more information, see the External PMOS Mode section.
23
COMP
DCDC_A
DC-to-DC Compensation Capacitor. Connect a 10 nF capacitor from this pin to ground. Used to regulate the
feedback loop of the Channel A dc-to-dc converter. Alternatively, if using an external compensation resistor,
place a resistor in series with a capacitor to ground from this pin. For more information, see the DC-to-DC
Converter Compensation Capacitors section and the AI
CC Supply Requirements—Slewing section.
