Maxim introduces the MAX5858, a dual, 10-bit, 300Msps DAC with integrated digital interpolation filters. This device integrates two, 10-bit DAC cores, 2x/4x programmable digital interpolation filters, divide-by-N clock output, and an internal reference. The >MAX5858 also features digital control of channel gain matching to >within plusmn> 0.4 dB in sixteen 0.05 dB steps. The MAX5858 is specified over the 2.7V to 3.3V operating range and has an extended output compliance voltage. At a 20 MHz output frequency (165 MHz sample rate), the >spurious-free dynamic range (SFDR) is 75 dBc. The adjacent channel leakage ratio (ACLR) is 69 dBc when the output frequency is 30.7 MHz (3.8 MHz channel). The interpolation filters lower the >input data rate and reduce the inherent DAC roll off. The MAX5858 is available in a 48-pin TQFP >package specified for the industrial temperature range (mn> 40deg>C to +85deg>C).p> B>url>www.maxim-ic.com; (408) 737-7600/url>/B>/t1>
