General 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-reconstruc-

tion 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 glitch-

ing and allow the MAX555 to achieve precise RF perfor-

mance with over 73dBc of spurious-free dynamic range

at 50Msps with f

OUT

= 3.1MHz, or 62dBc at 300Msps

with f

OUT

= 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.
