General Description
The MAX5180 contains two 10-bit, simultaneous-
update, current-output digital-to-analog converters
(DACs) designed for superior performance in communi-
cations 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 min-
imize unwanted spurious signal components at the out-
put. An on-board +1.2V bandgap circuit provides a
well-regulated, low-noise reference that can be dis-
abled for external reference operation.
The MAX5180/MAX5183 are designed to provide a high
level of signal integrity for the least amount of power dis-
sipation. 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 wake-up 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.
