Description
46
V
BOOST_C
Supply for Channel C Current Output Stage (see Figure 73). This is also the supply for the V
OUT_x stage, which is
regulated to 15 V by the dc-to-dc converter. To use the dc-to-dc feature of the device, connect as shown in
47
I
OUT_C
Current Output Pin for DAC Channel C.
48
COMP
DCDC_C
DC-to-DC Compensation Capacitor. Connect a 10 nF capacitor from this pin to ground. Used to regulate the
feedback loop of the Channel C dc-to-dc converter. Alternatively, if using an external compensation resistor,
place a resistor in series with a capacitor to ground from this pin (see the DC-to-DC Converter Compensation
CC Supply Requirements—Slewing sections in the Device Features section for more
information).
49
V
OUT_C
Buffered Analog Output Voltage for DAC Channel C.
50
+V
SENSE_C
Sense Connection for the Positive Voltage Output Load Connection for V
OUT_C.
51
CHARTC
HART Input Connection for DAC Channel C.
52
COMP
LV_C
Optional Compensation Capacitor Connection for V
OUT_C Output Buffer. Connecting a 220 pF capacitor between
this pin and the V
OUT_C pin allows the voltage output to drive up to 2 F. Note that the addition of this capacitor
reduces the bandwidth of the output amplifier, increasing the settling time.
53
AV
SS
Negative Analog Supply Pin.
54
I
OUT_D
Current Output Pin for DAC Channel D.
55
V
OUT_D
Buffered Analog Output Voltage for DAC Channel D.
56
V
BOOST_D
Supply for Channel D Current Output Stage (see Figure 73). This is also the supply for the V
OUT_x stage, which is
regulated to 15 V by the dc-to-dc converter. To use the dc-to-dc feature of the device, connect as shown in
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 (see the DC-to-DC Converter Compensation
CC Supply Requirements—Slewing sections in the Device Features section for more
information).
58
+V
SENSE_D
Sense Connection for the Positive Voltage Output Load Connection for V
OUT_D.
59
CHARTD
HART Input Connection for DAC Channel D.
60
COMP
LV_D
Optional Compensation Capacitor Connection for V
OUT_D Output Buffer. Connecting a 220 pF capacitor between
this pin and the V
OUT_D pin allows the voltage output to drive up to 2 F. Note that the addition of this capacitor
reduces the bandwidth of the output amplifier, increasing the settling time.
61
REFIN
External Reference Voltage Input.
62
REFOUT
Internal Reference Voltage Output. It is recommended to place a 0.1 F capacitor 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. See the Device Features 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. See the Device Features section.
EPAD
Exposed Pad. This exposed pad should be connected to the potential of the AV
SS pin, or, alternatively, it can be
left electrically unconnected. It is recommended that the pad be thermally connected to a copper plane for
enhanced thermal performance.
