The MAX5188 is a dual 8-bit, alternate-phase-update,
current-output digital-to-analog converter (DAC)
designed for superior performance in systems requiring
analog signal reconstruction with low distortion and
low-power operation. The MAX5191 provides equal
specifications, with on-chip output resistors for voltage-output operation. Both devices are designed for 10pV-s
glitch operation to reduce distortion and minimize
unwanted spurious signal components at the output. An
on-board +1.2V bandgap circuit provides a well-regulated,
low-noise reference that may be disabled for
external reference operation.
The MAX5188/MAX5191 are designed to provide a high
level of signal integrity for the least amount of power
dissipation. Both DACs operate from a +2.7V to +3.3V
single supply. Additionally, these DACs have three
modes of operation: normal, low-power standby, and
full shutdown. A full shutdown provides the lowest possible
power dissipation with a maximum shutdown current
of 1µA. A fast wake-up time (0.5µs) from standby
mode to full DAC operation allows for power conservation
by activating the DACs only when required.
The MAX5188/MAX5191 are available in a 28-pin QSOP
package and are specified for the extended (-40°C to
+85°C) temperature range. For pin-compatible 10-bit
versions, refer to the MAX5182/MAX5185 data sheet.
