4.1.3 MAX5134 DAC (Code Generator)
The MAX5134 DAC control section allows users to send a single DAC
value for a DC output or to pick from a few basic waveforms. Signal
levels are set in DAC codes (range of 0 to 65535) and are sent to all
four DAC outputs. See the table in the
Analog Signal Connections
section for respective output signal levels.
Note that the USB overhead encountered in the USB2PMB1 board
(through use of FTDI chipset’s software device driver) will throttle
throughput from the PC to the MAX5134 quad-DAC device (when
generating waveform signals) to approximately 2.6K DAC sampling
points per second. Refer to
Reference Schematic 5839 for more
information on performance results for the DAC and MAXREFDES24
reference design using a Xilinx development kit.
