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.
