Pin No.
Mnemonic
Description
49
IGATEC
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.
50
NC
No Connect. Do not connect to this pin.
51
CHARTC
HART Input Connection for DAC Channel C. For more information, see the HART Connectivity section.
52
NC
No Connect. Do not connect to this pin.
53
AGND
Ground Reference Point for Analog Circuitry. This pin must be connected to 0 V.
54
I
OUT_D
Current Output Pin for DAC Channel D.
55
NC
No Connect. Do not connect to this pin.
56
V
BOOST_D
Supply for Channel D Current Output Stage (see Figure 48). To use the dc-to-dc converter, connect this pin
as shown in Figure 55.
57
COMP
DCDC_D
DC-to-DC Compensation Capacitor. Connect a 10 nF capacitor from this pin to ground. Used to regulate the
feedback loop of the Channel D 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.
58
IGATED
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.
59
CHARTD
HART Input Connection for DAC Channel D. For more information, see the HART Connectivity section.
60
NC
No Connect. Do not connect to this pin.
61
REFIN
External Reference Voltage Input.
62
REFOUT
Internal Reference Voltage Output. It is recommended that a 0.1 F capacitor be placed between REFOUT
and REFGND.
REFOUT must be connected to REFIN to use the internal reference.
63
R
SET_D
An external, precision, low drift, 15 k current setting resistor can be connected to this pin to improve the
I
OUT_D temperature drift performance. For more information, see the External Current Setting Resistor section.
64
R
SET_C
An external, precision, low drift, 15 k current setting resistor can be connected to this pin to improve the
I
OUT_C temperature drift performance. For more information, see the External Current Setting Resistor section.
EPAD
Exposed Pad. The exposed paddle should be connected to AGND, or, alternatively, it can be left electrically
unconnected. It is recommended that the paddle be thermally connected to a copper plane for enhanced
thermal performance.
