Description
Supply for Channel C Current Output Stage (see Figure 73). This is also the supply for the V
regulated to 15 V by the dc-to-dc converter. To use the dc-to-dc feature of the device, connect as shown in
Figure 80.
Current Output Pin for DAC Channel 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
Capacitors and AI
information).

External Reference Voltage Input.
Internal Reference Voltage Output. It is recommended to place a 0.1 μF capacitor between REFOUT and
REFGND.
An external, precision, low drift 15 kΩ current setting resistor can be connected to this pin to improve the I
temperature drift performance. See the Device Features section.

Exposed Pad. This exposed pad should be connected to the potential of the AV
left electrically unconnected. It is recommended that the pad be thermally connected to a copper plane for
enhanced thermal performance.
