Valid in the output voltage range of (AGND + 0.5 V) to (V
DD
− 0.5 V). Output is unloaded.

Includes linearity, offset, and gain drift.

Guaranteed by design and characterization. Not production tested.
5
The DAC architecture gives a fixed linear voltage output range of 0 V to 30 V if
R_SEL
is held high and 0 V to 60 V if
R_SEL
is held low. As the output voltage range is
limited by output amplifier compliance, V
DD
should be set to at least 0.5 V higher than the maximum output voltage to ensure compliance.
6
If the die temperature exceeds 110°C, the AD5501 enters a temperature power-down mode putting the DAC output into a high impedance state thereby removing
the short-circuit condition. Overheating caused by long term short-circuit condition(s) is detected by an integrated thermal sensor. After power-down, the AD5501
remains powered down until a software power-up command is executed.
