MAXIM MAX5186, MAX5189 Technical data

General Description

The MAX5186 contains two 8-bit, simultaneous-update,
current-output digital-to-analog converters (DACs)
designed for superior performance in communications
systems requiring analog signal reconstruction with low
distortion and low-power operation. The MAX5189 pro­vides equal specifications, with on-chip precision resis­tors for voltage output operation. The MAX5186/
MAX5189 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 MAX5186/MAX5189 are designed to provide a high
level of signal integrity for the least amount of power dissi­pation. Both DACs operate from a single supply voltage
of 2.7V to 3.3V. Additionally, these DACs have three
modes of operation: normal, low-power standby, and
complete 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 allows power conservation by activating the
DACs only when required.

The MAX5186/MAX5189 are packaged in a 28-pin
QSOP and are specified for the extended (-40°C to
+85°C) temperature range. For higher resolution, dual
10-bit versions, refer to the MAX5180/MAX5183 data
sheet.
