MAX5180BEEI
Dual, 10-Bit, 40MHz, Current/Voltage Simultaneous-Output DACs
General DescriptionThe MAX5180 contains two 10-bit, simultaneous-
update, current output digital-to-analog converters
(DACs) designed for superior performance in communi-
cations systems requiring analog signal reconstruction
with low distortion and low-power operation. The
MAX5183 provides equal specifications, with on-chip
precision resistors for voltage output operation. Both
devices are designed for 10pVs glitch operation to min-
imize unwanted spurious signal components at the out-
put. An on-board +1.2V bandgap circuit provides a
well-regulated, low-noise reference that can be dis-
abled for external reference operation.
The MAX5180/MAX5183 are designed to provide a high
level of signal integrity for the least amount of power dis-
sipation. Both DACs operate from a single supply 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 1µA (max) shutdown current. A
fast wake-up time (0.5µs) from standby mode to full DAC
operation conserves power by activating the DACs only
when required.
The MAX5180/MAX5183 are packaged in a 28-pin QSOP
and are specified for the extended (-40°C to +85°C)
temperature range. For lower-resolution, dual 8-bit
versions, refer to the MAX5186/MAX5189 data sheet.

Dual, 10-Bit, 40MHz, Current/Voltage
Simultaneous-Output DACs
Detailed DescriptionThe MAX5180/MAX5183 are dual 10-bit digital-to-ana-
log 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
MAX5183’s voltage output operation features matched
400Ωon-chip resistors that convert the current array
current into a voltage.
Internal Reference and Control AmplifierThe MAX5180/MAX5183 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 external refer-
ence input or an integrated reference output. If RENis
connected to AGND, the internal reference is selected
and REFO provides a +1.2V output. Due to its limited
10µA output drive capability, REFO must be buffered
with an external amplifier if heavier loading is required.
The MAX5180/MAX5183 also employ a control amplifier
designed to simultaneously regulate the full-scale out-
put current (IFS) for both outputs of the devices. 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 on the MAX5180 (Figure 2).
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.
The MAX5183 converts each output current (DAC1 and
DAC2) into an output voltage (VOUT1, VOUT2) with two
internal, ground-referenced 400Ωload resistors. Using
the internal +1.2V reference voltage, the MAX5183’s
integrated reference output current resistor (RSET=
9.6kΩ) sets IREFto 125µA and IFSto 1mA.
