Detailed Description
Architecture
The MAX5876 high-performance, 12-bit, dual current-
steering DAC (Figure 1) operates with DAC update rates
up to 250Msps. The converter consists of input registers
and a demultiplexer for single-port operation, followed by
a current-steering array. During operation, the input data
registers demultiplex the single-port data bus. The cur-
rent-steering array generates differential full-scale cur-
rents in the 2mA to 20mA range. An internal
current-switching network, in combination with external
50
termination resistors, converts the differential output
currents into dual differential output voltages with a 0.1V
to 1V peak-to-peak output voltage range. An integrated
+1.2V bandgap reference, control amplifier, and user-
selectable external resistor determine the data convert-
er’s full-scale output range.
Reference Architecture and Operation
The MAX5876 supports operation with the internal
+1.2V bandgap reference or an external reference volt-
age source. REFIO serves as the input for an external,
low-impedance reference source. REFIO also serves as
a reference output when the DAC operates in internal
reference mode. For stable operation with the internal
reference, decouple REFIO to GND with a 1F capaci-
tor. Due to its limited output drive capability, buffer
REFIO with an external amplifier when driving large
external loads.
