POWER CYCLE HYSTERESIS

By power cycling large numbers of samples, the power cycle

hysteresis can be determined. To keep this measurement

independent of other variables and environmental effects, the

power cycle testing was performed using a high precision

measurement system, including an ultrastable oil bath.

Figure 122 shows the power cycle hysteresis. The units were

powered down for approximately four hours and then powered

up. The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/

ADR4550 do not have any power cycle hysteresis even after a

long power-down period, making these devices very suitable for

equipment which must maintain its calibration accuracy

between power cycles.
