Detailed Description

The MAX5441–MAX5444 voltage-output, 16-bit digital-

to-analog converters (DACs) offer full 16-bit perfor-

mance with less than 2LSB integral linearity error and

less than 1LSB differential linearity error, thus ensuring

monotonic performance. Serial data transfer minimizes

the number of package pins required.

The MAX5441–MAX5444 are composed of two

matched DAC sections, with a 12-bit inverted R-2R

DAC forming the 12 LSBs and the four MSBs derived

from 15 identically matched resistors. This architecture

allows the lowest glitch energy to be transferred to the

DAC output on major-carry transitions. It also lowers the

DAC output impedance by a factor of eight compared
