MAX5190BEEG+T
8-Bit, 40MHz, Current/Voltage-Output DACs
General Description
The MAX5187 is an 8-bit, current-output digital-to-ana-
log converter (DAC) designed for superior performance
in signal reconstruction or arbitrary waveform genera-
tion applications requiring analog signal reconstruction
with low distortion and low-power operation. The volt-
age-output MAX5190 provides equal specifications,
with on-chip precision resistors for voltage output oper-
ation. Both devices are designed for a 10pVs glitch
operation to minimize unwanted spurious signal com-
ponents at the output. An on-board +1.2V bandgap cir-
cuit provides a well-regulated, low-noise reference that
can be disabled for external reference operation.
The MAX5187/MAX5190 are designed to provide a high
level of signal integrity for the least amount of power
dissipation. They operate from a single supply of +2.7V
to +3.3V. Additionally, these DACs have three modes of
operation: normal, low-power standby, and full shut-
down, which provides the lowest possible power dissi-
pation with a 1µA (max) shutdown current. A fast
wake-up time (0.5µs) from standby mode to full DAC
operation allows for power conservation by activating
the DAC only when required.
The MAX5187/MAX5190 are packaged in a 24-pin
QSOP and are specified for the extended (-40°C to
+85°C) temperature range. For higher resolution, 10-bit
versions, see the MAX5181/MAX5184 data sheet.

Detailed Description

The MAX5187/MAX5190 are 8-bit DACs capable of
operating with clock speeds up to 40MHz. Each con-
verter consists of separate input and DAC registers, fol-
lowed by a current-source array capable of generating
up to 1.5mA full-scale output current (Figure 1). An inte-
grated +1.2V voltage reference and control amplifier
determine the data converters’ full-scale output cur-
rents/voltages. Careful reference design ensures close
gain matching and excellent drift characteristics. The
MAX5190’s voltage-output operation features matched
400Ωon-chip resistors that convert the current array
current into a voltage.
Internal Reference
and Control Amplifier

The MAX5187/MAX5190 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 DGND, 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 MAX5187/MAX5190 also employ a control amplifi-
er, designed to simultaneously regulate the full-scale
output current (IFS) for both outputs of the devices. The
output current is calculated as follows:
IFS = 8 x 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 MAX5187 (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 MAX5190 converts this output current into a differ-
ential output voltage (VOUT) with two internal, ground-
referenced 400Ωload resistors. Using the internal
+1.2V reference voltage, the MAX5190’s integrated
reference output current resistor (RSET = 9.6kΩ) sets
IREFto 125µA and IFSto 1mA.
