Dual, 10-Bit, 40MHz, Current/Voltage
Simultaneous-Output DACs
General Description
Features
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. Both
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. Both 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.
