General Description

The MAX5180 contains two 10-bit, simultaneous­update, current-output digital-to-analog converters
(DACs) designed for superior performance in communi­cations systems requiring analog signal reconstruction
with low distortion and low-power operation. The
MAX5183 provides equal specifications, with on-chip
precision resistors for voltage output operation. The
devices are designed for 10pVs glitch operation to min­imize unwanted spurious signal components at the out­put. An on-board 1.2V bandgap circuit provides a
well-regulated, low-noise reference that can be dis­abled for external reference operation.

The MAX5180/MAX5183 are designed to provide a high
level of signal integrity for the least amount of power dis­sipation. The DACs operate from a single supply of 2.7V
to 3.3V. Additionally, these DACs have three modes of
operation: normal, low-power standby, and complete
shutdown, which provides the lowest possible power dis­sipation with 1µA (max) shutdown current. A fast wake­up time (0.5µs) from standby mode to full DAC operation
conserves power by activating the DACs only when
required.

The MAX5180/MAX5183 are packaged in a 28-pin QSOP
and are specified for the extended (-40°C to +85°C)
temperature range. For lower-resolution, dual 8-bit
versions, refer to the MAX5186/MAX5189 data sheet.
