MAX5893 Datasheet, PDF (7/32 Pages) Maxim Integrated Products – 12-Bit, 500Msps Interpolating and Modulating Dual DAC with CMOS Inputs

12-Bit, 500Msps Interpolating and Modulating
Dual DAC with CMOS Inputs
Typical Operating Characteristics
(DV_DD1.8 = AV_DD1.8 = 1.8V, AV_CLK = AV_DD3.3 = DV_DD3.3 = 3.3V, modulator off, 2x interpolation, output is transformer-coupled to
50Ω load, T_A = +25°C, unless otherwise noted.)
