Dual, 10-Bit, 40MHz Current/Voltage

Alternate-Phase Output DACs

General Description

Features

The MAX5182 is a dual, 10-bit, alternate-phase-update,

current-output digital-to-analog converter (DAC)

designed for superior performance in systems requiring

analog signal reconstruction with low distortion and

low-power operation. The MAX5185 provides equal

specifications with on-chip output resistors for voltage-

output operation. Both devices are designed for 10pV-s

glitch operation, to reduce distortion and minimize

unwanted spurious signal components at the output. An

on-board +1.2V bandgap circuit provides a well-regu-

lated, low-noise reference that can be disabled for

external reference operation.

o +2.7V to +3.3V Single-Supply Operation

o Wide Spurious-Free Dynamic Range: 70dB at

= 2.2MHz

OUT

o Fully-Differential Outputs for Each DAC

0.ꢀ5 FSR ꢁain Mismatch Betꢂeen DAC Outputs

o Loꢂ-Current Standby or Full-Shutdoꢂn Modes

o Internal +1.2V Loꢂ-Noise Bandgap Reference

o Small 28-Pin QSOP Package

The MAX5182/MAX5185 are designed to provide a high

level of signal integrity for the least amount of power dis-

sipation. Both DACs operate from a +2.7V to +3.3V sin-

gle supply. Additionally, these DACs have three modes

of operation: normal, low-power standby, and complete

shutdown. A full shutdown provides the lowest possible

power dissipation with a maximum shutdown current of

1µA. Fast wake-up time (0.5µs) from standby mode to

full DAC operation allows for power conservation by

activating the DACs only when required.
