Typical specifications represent average readings at 25°C, VDD = 62 V and VLOGIC = 5 V.
2
Valid in output voltage range of (VDD 0.5 V) to (AGND + 0.5 V). Outputs are unloaded.
3
Includes linearity, offset, and gain drift.
4
Guaranteed by design and characterization. Not production tested.
5
VOUTX refers to VOUTA, VOUTB, VOUTC, or VOUTD.
6
DAC code = 32 for 60 V mode; DAC code = 64 for 30 V mode.
7
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.
8
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.
AC CHARACTERISTICS
VDD = 10 V to 62 V; VLOGIC = 2.3 V to 5.5 V; RL = 60 k; CL = 200 pF; 40°C < TA < +105°C, unless otherwise noted.
