Detailed Description
Architecture
The MAX5887 is a high-performance, 14-bit, current-
steering DAC (Figure 1) capable of operating with clock
speeds up to 500MHz. The converter consists of sepa-
rate input and DAC registers, followed by a current-
steering circuit. This circuit is capable of generating
differential full-scale currents in the range of 2mA to
20mA. An internal current-switching network in combi-
nation with external 50
termination resistors convert
the differential output currents into a differential output
voltage with a peak-to-peak output voltage range of
0.1V to 1V. An integrated 1.2V bandgap reference, con-
trol amplifier, and user-selectable external resistor
determine the data converter’s full-scale output range.
Reference Architecture and Operation
The MAX5887 supports operation with the on-chip 1.2V
bandgap reference or an external reference voltage
source. REFIO serves as the input for an external, low-
impedance reference source, and as the output if the
DAC is operating with the internal reference. For stable
operation with the internal reference, REFIO should be
decoupled to AGND with a 0.1F capacitor. Due to its
limited output drive capability, REFIO must be buffered
with an external amplifier, if heavier loading is required.
The MAX5887’s reference circuit (Figure 2) employs a
control amplifier, designed to regulate the full-scale
current IOUT for the differential current outputs of the
DAC. Configured as a voltage-to-current amplifier, the
output current can be calculated as follows:
IOUT = 32 IREFIO - 1LSB
IOUT = 32 IREFIO - (IOUT / 214)
where IREFIO is the reference output current (IREFIO =
VREFIO/RSET) and IOUT is the full-scale output current of
the DAC. Located between FSADJ and DACREF, RSET
is the reference resistor, which determines the amplifi-
er’s output current for the DAC. See Table 1 for a matrix
of different IOUT and RSET selections.
