MAX5141 Maxim, MAX5141 Datasheet - Page 7

• Manufacturer Part Number: MAX5141
• Description: +3V/+5V / Serial-Input / Voltage-Output / 14-Bit DACs
• Manufacturer: Maxim

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
