MAX5191BEEI
Dual / 8-Bit / 40MHz / Current/Voltage / Alternate-Phase Output DACs
General Description
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 10pVs
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 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 pos-
sible power dissipation with a maximum shutdown cur-
rent of 1µA. A fast wake-up time (0.5µs) from standby
mode to full DAC operation allows for power conserva-
tion 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.

Detailed Description
The MAX5188/MAX5191 are dual 8-bit digital-to-analog
converters (DACs) capable of operating with clock
speeds up to 40MHz. Each of these dual converters
consists of separate input and DAC registers, followed
by a current-source array capable of generating up to
1.5mA full-scale output current (Figure 1). An integrat-
ed +1.2V voltage reference and control amplifier deter-
mine the data converters’ full-scale output currents/
voltages. Careful reference design ensures close gain
matching and excellent drift characteristics. The
MAX5191’s voltage output operation features matched
400Ωon-chip resistors that convert the current from the
current array into a voltage.
Internal Reference
and Control Amplifier
The MAX5188/MAX5191 provide an integrated
50ppm/°C, +1.2V, low-noise bandgap reference that
can be disabled and overridden by an external refer-
ence voltage. REFO serves either as an input for an
external reference or as an output for the integrated ref-
erence. If RENis connected to DGND, the internal ref-
erence is selected and REFO provides a +1.2V output.
Due to its limited 10µA output drive capability, the
REFO pin must be buffered with an external amplifier if
heavier loading is required.
The MAX5188/MAX5191 also employ a control amplifi-
er, designed to simultaneously regulate the full-scale
output current IFSfor both MAX5188/MAX5191 outputs.
The output current is calculated as follows:
IFS= 8 ·IREF
where IREFis the reference output current (IREF=
VREFO / RSET) and IFSis the full-scale output current.
RSETis the reference resistor that determines the
amplifier’s output current (Figure 2) on the MAX5188.
This current is mirrored into the current-source array,
where it is equally distributed between matched current
segments and summed to valid output current readings
for the DACs.
Inside the MAX5191, each output current (DAC1 and
DAC2) is converted to an output voltage (VOUT1,
VOUT2) with two internal, ground-referenced, 400Ωload
resistors. Using the internal +1.2V reference voltage,
the integrated reference output current resistor of the
MAX5191 (RSET= 9.6kΩ) sets IREFto 125µA and IFS to
1mA.
