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

Figure 115. AD5381 Evaluation Software—AD5381 Option Selected.

A convenient method of verifying and customizing the signal

chains shown in Figure 112 and 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.

When configuring evaluation boards around the AD8264-EVALZ,

always be certain to refer to the latest revision of the AD5381

and/or AD9228 data sheets for hardware revisions or updates.

The EVAL-AD5380SDPZ (a 40-channel DAC) connects to the

EVAL-SDP-CB1Z and includes a software evaluation program

to control the DAC. The AD5380 evaluation software allows the

user to configure and program DAC parameters such 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. For DAC user application information, refer

to UG-757.

The ADC evaluation kit includes the AD9228-65EBZ board and

the HSC-ADC-FIFO5 board to decode the ADC output. The kit

also leverages the capabilities of VisualAnalog®, powerful sim-

ulation and data analysis software that enables the user to run

FFTs and to perform real-time capture of the output levels.
