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.
