Typical specifications represent average readings at 25°C, VDD = 62 V and VLOGIC = 5 V.

Valid in output voltage range of (VDD − 0.5 V) to (AGND + 0.5 V). Outputs are unloaded.

Includes linearity, offset, and gain drift.

Guaranteed by design and characterization. Not production tested.

VOUTX refers to VOUTA, VOUTB, VOUTC, or VOUTD.

DAC code = 32 for 60 V mode; DAC code = 64 for 30 V mode.

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, VDD should be set to at least 0.5 V higher than the maximum output voltage to ensure compliance.

If the die temperature exceeds 110°C, the AD5504 enters a temperature power-down mode putting the DAC outputs 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 AD5504

stays powered down until a software power-up command is executed.
