NOTES
1Typical specifications represent average readings measured at 25
∞C.
2DAC Output Equation: V
OUT = VREFL + [(VREFH – VREFL)
D/2
N], where D = data loaded in corresponding DAC Register A, B, C, D, and N equals the number of bits;
AD5582 = 12 bits, AD5583 = 10 bits. One LSB step voltage = (V REFH – VREFL)/4096 V and (VREFH – VREFL)/1024 V for AD5582 and AD5583, respectively.
3The first two codes (000
H, 001H) of the AD5583 and the first four codes (000 H, 001H, 002H, 003H) of the AD5582 are excluded from the linearity error measurement
in single-supply operation.
4These parameters are guaranteed by design and not subject to production testing.
5Dual-supply operation, V
REFL = VSS, exclude the lowest eight codes for the AD5582 and two codes for the AD5583 for INL and DNL errors.
6Short circuit output and supply currents are 24 mA and 25 mA, respectively.
7Part is stable under any capacitive loading conditions.
8The settling time specification does not apply for negative-going transitions within the last 3 LSBs of ground in single-supply operation.
Specifications subject to change without notice.
