Dual, 8-Bit, 40MHz, Current/Voltage,

Simultaneous-Output DACs

General Description

Features

The MAX5186 contains two 8-bit, simultaneous-update,

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 MAX5189 pro-

vides equal specifications, with on-chip precision resis-

tors for voltage output operation. The MAX5186/

MAX5189 are designed for a 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 dis-

abled for external reference operation.

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

o Wide Spurious-Free Dynamic Range:

70dB at f = 2.2MHz

OUT

o Fully Differential Outputs for Each DAC

0.ꢀ5 FSR ꢁain Mismatch

0.ꢂꢀꢃ Phase Mismatch

o Low-Current Standby or Full Shutdown Modes

o Internal +ꢂ.2V, Low-Noise Bandgap Reference

o Small 28-Pin QSOP Package

The MAX5186/MAX5189 are designed to provide a high

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

pation. Both DACs operate from a single supply voltage

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 a 1µA (max) shutdown current. A

fast wake-up time (0.5µs) from standby mode to full DAC

operation allows power conservation by activating the

DACs only when required.
