MAX555数据手册集成电路（IC）的数模转换器（DAC）规格书PDF

描述 Description

The MAX555 is an advanced, monolithic, 12-bit digital-to-analog converter (DAC) with complementary 50Ω 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 73dBc of spurious-free dynamic range at 50Msps with fOUT = 3.1MHz, or 62dBc at 300Msps with fOUT = 18.6MHz.
The MAX555 operates from a single -5.2V supply and dissipates 980mW (nominal). It comes in a 64-pin TQFP package with exposed paddle for enhanced thermal dissipation.
