Figure 114. Evaluation Setup for DC-Coupled Analog Front-End Pulse Processing Application Using the AD8264

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.
