AD5243/AD5248

This demonstrates that constantly biasing the potentiometer is

not an impractical approach. Most portable devices do not

require the removal of batteries for the purpose of charging.

Although the resistance setting of the AD5243/AD5248 is lost

when the battery needs replacement, such events occur rather

infrequently such that this inconvenience is justified by the

lower cost and smaller size offered by the AD5243/AD5248. If

and when total power is lost, the user should be provided with a

means to adjust the setting accordingly.

EVALUATION BOARD

CONSTANT BIAS TO RETAIN RESISTANCE SETTING

An evaluation board, along with all necessary software, is avail-

able to program the AD5243/AD5248 from any PC running

Windows 98/2000/XP. The graphical user interface, as shown in

Figure 44, is straightforward and easy to use. More detailed

information is available in the user manual, which comes with

the board.

For users who desire nonvolatility but cannot justify the addi-

tional cost for the EEMEM, the AD5243/AD5248 may be

considered as low cost alternatives by maintaining a constant

bias to retain the wiper setting. The AD5243/AD5248 are

designed specifically with low power in mind, which allows low

power consumption even in battery-operated systems. The

graph in Figure 43 demonstrates the power consumption from a

3.4 V 450 mAhr Li-Ion cell phone battery, which is connected to

the AD5243/AD5248. The measurement over time shows that

the device draws approximately 1.3 µA and consumes negligible

power. Over a course of 30 days, the battery is depleted by less

than 2ꢀ, the majority of which is due to the intrinsic leakage

current of the battery itself.

The AD5243/AD5248 start at midscale upon power-up. To

increment or decrement the resistance, the user may simply

move the scrollbars on the left. To write any specific value, the

user should use the bit pattern in the upper screen and press the

Run button. The format of writing data to the device is shown

in Table 9. To read the data out from the device, the user can

simply press the Read button. The format of the read bits is

shown in Table 10.
