General Description
The MAX555 is an advanced, monolithic, 12-bit digital-
to-analog converter (DAC) with complementary 50
Ω
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.
