MAX5441–MAX5444
+3V/+5V, Serial-Input,
Voltage-Output, 16-Bit DACs
_______________________________________________________________________________________ 7
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
