MAX5182BEEI+

P1-P3P4-P6P7-P9P10-P12P13-P14
General Description
The MAX5182 is a dual, 10-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 MAX5185 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-regu-
lated, low-noise reference that can be disabled for
external reference operation.
The MAX5182/MAX5185 are designed to provide a high
level of signal integrity for the least amount of power dis-
sipation. Both DACs operate from a +2.7V to +3.3V sin-
gle supply. Additionally, these DACs have three modes
of operation: normal, low-power standby, and complete
shutdown. A full shutdown provides the lowest possible
power dissipation with a maximum shutdown current of
1µA. 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 MAX5182/MAX5185 are available in a 28-pin QSOP
package and are specified for the extended (-40°C to
+85°C) temperature range. For pin-compatible 8-bit
versions, refer to the MAX5188/MAX5191 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.
