General Description

The MAX5181 is a 10-bit, current-output digital-to-ana-

log converter (DAC) designed for superior performance

in signal reconstruction or arbitrary waveform genera-

tion applications requiring analog signal reconstruction

with low distortion and low-power operation. The

MAX5184 provides equal specifications, with on-chip

precision resistors for voltage-output operation. The

MAX5181/MAX5184 are designed for a 10pVs glitch

operation to minimize unwanted spurious signal com-

ponents at the output. An on-board +1.2V bandgap cir-

cuit provides a well-regulated, low-noise reference that

can be disabled for external reference operation.

The devices are designed to provide a high level of sig-

nal integrity for the least amount of power dissipation.

They operate from a single +2.7V to +3.3V supply.

Additionally, these DACs have three modes of opera-

tion: normal, low-power standby, and full 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 facili-

tates power conservation by activating the DAC only

when required.

The MAX5181/MAX5184 are available in 24-pin QSOP

packages and are specified for the extended (-40°C to

+85°C) temperature range. For lower resolution, 8-bit

versions, refer to the MAX5187/MAX5190 data sheet.
