Detailed Description

The MAX5141–MAX5144 voltage-output, 14-bit digital-

to-analog converters (DACs) offer full 14-bit perfor-

mance with less than 1LSB 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 MAX5141–MAX5144 are composed of two

matched DAC sections, with a 10-bit inverted R-2R

DAC forming the ten 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
