Figure 115. AD5381 Evaluation Software
A convenient method of verifying and customizing the signal
chains shown in Figure 112 or Figure 113 is by ordering the
corresponding evaluation boards available on www.analog.com.
The AD8264-EVALZ is a platform through which the user can
quickly become familiar with the features and performance
capabilities of the AD8264. See the Evaluation Board section for
more information.
The EVAL-AD5381EB (40-channel DAC) includes a parallel PC
interface and software evaluation program to control the DAC.
The AD5381evaluation software allows the user to configure
and program such DAC parameters as input codes, offset level,
and output range based on a 2.5 V or 1.25 V reference. For
example, as shown in Figure 114, the reference can be set to 1.25 V,
with a 0 V to 1.25 V output range to drive the GNHx inputs.
The ADC evaluation kit includes the AD9228-65EBZ board and
HSC-ADC-FIFO5 board to decode the ADC output. It also
leverages the capabilities of VisualAnalog, powerful simulation
and data analysis software that enables the user to run FFTs and
to do real-time capture of the output levels.
