10-Bit, 40MHz, Current/Voltage-Output DACs
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
