MAX555 Datasheet | Maxim Integrated

Description The MAX555 is an advanced, monolithic, 12-bit digitalto-analog converter (DAC) with plementary 50 Ω outputs. Fabricated using an oxide-isolated bipolar process, the MAX555 is designed for signal-reconstruction applications at an output update rate of 300Msps. It incorporates an analog multiplying function with 10MHz useable input bandwidth. The voltage-output DAC uses precision laser trimming to achieve 12-bit accuracy with ±1/2LSB integral and differential linearity (±0.012% FS). Absolute gain error is a low 1% of full scale. Full-scale transitions occur in less than 0.5ns. Internal registers and a unique decoder reduce glitching and allow the MAX555 to achieve precise RF performance with over 73d Bc of spurious-free dynamic range at 50Msps with f OUT = 3.1MHz, or 62d Bc at 300Msps with f OUT = 18.6MHz. The MAX555 operates from a single -5.2V supply and dissipates 980m W (nominal). It es in a 68-pin thermally enhanced PLCC package capable of accepting a heatsink. ______________Ordering Information PART MAX555CQK TEMP.
