Description
Supply for DC-to-DC Circuitry. The voltage range is from 4.5 V to 5.5 V.
Supply for Channel C Current Output Stage (see Figure 71). This pin is also the supply for the V
which is regulated to 15 V by the dc-to-dc converter. To use the dc-to-dc converter, connect this pin as
shown in Figure 77.
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. For more information, see the DC-to-DC
Converter Compensation Capacitors section and the AI

±3.0 V of AGND for specified operation.
Optional Compensation Capacitor Connection for V
between this pin and the V
of this capacitor reduces the bandwidth of the output amplifier, increasing the settling time.
Negative Analog Supply Pin. The voltage range is from −10.8 V to −26.4 V.
Current Output Pin for DAC Channel D.
Buffered Analog Output Voltage for DAC Channel D.
Supply for Channel D Current Output Stage (see Figure 71). This pin is also the supply for the V
which is regulated to 15 V by the dc-to-dc converter. To use the dc-to-dc converter, connect this pin as
shown in Figure 77.

External Reference Voltage Input.
Internal Reference Voltage Output. It is recommended that a 0.1 µF capacitor be placed between REFOUT
and REFGND.
