General Description

The MAX5187 is an 8-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 volt-

age-output MAX5190 provides equal specifications,

with on-chip precision resistors for voltage output oper-

ation. Both devices 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 MAX5187/MAX5190 are designed to provide a high

level of signal integrity for the least amount of power

dissipation. They operate from a single supply of +2.7V

to +3.3V. Additionally, these DACs have three modes of

operation: normal, low-power standby, and full shut-

down, which provides the lowest possible power dissi-

pation with a 1µA (max) shutdown current. A fast

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

operation allows for power conservation by activating

the DAC only when required.

The MAX5187/MAX5190 are packaged in a 24-pin

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

+85°C) temperature range. For higher resolution, 10-bit

versions, see the MAX5181/MAX5184 data sheet.
