AD5726

APPLICATIONS

Figure 24 (symmetrical bipolar operation) shows the AD5726

configured for 10 V operation. ꢀee the AD688 datasheet for a

full explanation of the reference operation.

POWER-UP SEQUENCE

To prevent CMOꢀ latch-up conditions, powering AV_DD, AV_ꢀꢀ,

and GND prior to any reference voltages is recommended. The

ideal power-up sequence is GND, AV_ꢀꢀ, AV_DD, V_REFP, V_REFN, and

the digital inputs. Noncompliance with the power-up sequence

over an extended period can elevate the reference currents and

eventually damage the device. On the other hand, if the non-

compliant power-up sequence condition is as short as a few

milliseconds, the device can resume normal operation without

damage once AV_DD/AV_ꢀꢀare powered up.

Adjustments may not be necessary for many applications

because the AD688 is a very high accuracy reference. However,

if additional adjustments are required, adjust the AD5726 full-

scale first. Begin by loading the digital full-scale code (0xFFF).

Then, modify the gain adjust potentiometer to attain a DAC

output voltage of 9.9976 V. Next, alter the balance adjust to set

the midscale output voltage to 0.000 V.

The 0.2 μF bypass capacitors shown at their reference inputs in

Figure 24 should be used whenever 10 V references are used.

Applications with single references or references to 5 V may

not require the 0.2 μF bypassing. The 6.2 Ω resistor in series

with the output of the reference amplifier keeps the amplifier

from oscillating with the capacitive load. This has been found to

be large enough to stabilize this circuit. Larger resistor values

are acceptable if the drop across the resistor does not exceed a V_BE.

Assuming a minimum V_BEof 0.6 V and a maximum current of

2.75 mA, the resistor should be under 200 Ω for the loading of a

single AD5726.

REFERENCE CONFIGURATION

Output voltage ranges can be configured as either unipolar or

bipolar, and within these choices, a wide variety of options

exists. The unipolar configuration can be either a positive (as

shown in Figure 23) or a negative voltage output. The bipolar

configuration can be either symmetrical (as shown in Figure 24)

or nonsymmetrical.

Using two separate references is not recommended. Having two

references may cause different drifts with time and temperature,

whereas with a single reference, most drifts track.

REFN

Unipolar positive full-scale operation can usually be set by a

reference with the correct output voltage. This is preferable to

using a reference and dividing down to the required value. For a

10 V full-scale output, the circuit can be configured as shown in

Figure 25. In this configuration, the full-scale value is first set by

adjusting the 10 kΩ resistor for a full-scale output of 9.9976 V.
