The MAX5181 is a 10-bit, current-output digital-to-analog
converter (DAC) designed for superior performance
in signal reconstruction or arbitrary waveform generation
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 10pV-s 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 disabled for external reference operation.
The devices are designed to provide a high level of signal
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 operation:
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 facilitates
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. Additionally, the MAX5184
is also available in a 24-pin thin QFN with exposed paddle
(EP) and is specified for the extended (-40°C to
+85°C) temperature range. For lower resolution, 8-bit
versions, refer to the MAX5187/MAX5190 data sheet.
