4 / 20 page  DAC8412/DAC8413 Data Sheet Rev. G | Page 4 of 20 Parameter Symbol Conditions Min Typ Max Unit SUPPLY CHARACTERISTICS Power Supply Sensitivity PSS 14.25 V ≤ VDD ≤ 15.75 V 150 ppm/V Positive Supply Current IDD VREFH = 2.5 V 8.5 12 mA Negative Supply Current ISS −10 −6.5 mA Power Dissipation PDISS 330 mW 1 All supplies can be varied ±5%, and operation is guaranteed. Device is tested with nominal supplies. 2 Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed. 3 All parameters are guaranteed by design. 4 All input control signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V. VDD = VLOGIC = +5.0 V ± 5%, VSS = 0.0 V, VREFH = +2.5 V, VREFL = 0.0 V, VSS = –5.0 V ± 5%, VREFL = −2.5 V, −40°C ≤ TA ≤ +85°C, unless otherwise noted.1 Table 2.
